How to Choose The Best Trees & Shrubs for Coastal Gardens

by Arundel Arboretum on Mar 03, 2025
Dreaming about a beautiful coastal garden but struggling with salty winds and poor soil? Growing a garden in a seaside environment is nothing like planting in a sheltered inland space. The very things that make coastal living so desirable and beautiful – the fresh sea air, coastal breezes, and sunny shores – can be challenging for many plants. But with some expert guidance and right choices, your coastal garden can become a lush paradise. In this guide, you’ll find recommendations for the best trees and shrubs for coastal gardens in the UK and answers to the most common questions about growing a coastal garden. The Challenges of Coastal Gardening Why do some plants struggle to grow in coastal conditions? It’s because of the harsh conditions that make it difficult for them to thrive. The major challenges of coastal areas are: Salt Exposure One of the biggest challenges in a coastal garden is salt exposure from both the soil and the air. While some plants are adapted to it, others struggle to survive. Here is why: Osmotic Stress: High salt concentrations in the soil create osmotic stress which makes it harder for the roots to absorb water. The plant end up dehydrated and wilted. Soil Toxicity: Sodium and chloride build up in the roots and block the uptake of beneficial minerals. This weakens the plant, damages the roots, and scorches the leaves. Salt Build-Up: Airborne salt lands on plants, draws moisture out and causes leaf scorch. The layer of salt also blocks sunlight and affects photosynthesis. Coastal Winds All winds can be tough on plants and cause stress and damage, but coastal winds bring unique challenges that make them even more harmful. Coastal winds are: Stronger & More Consistent: With no natural barriers, open coastal landscapes are fully exposed and winds hit with full force More Damaging: Coastal winds carry tiny salt particles that land on plants, dehydrate them, and burn their leaves. In sandy areas, they carry sand particles that cause abrasion and physical damage. Constantly Changing: Coastal winds frequently change their direction which makes it harder for the plants to adapt and grow in one stable direction. Difficult Soil Types Soil types in coastal areas can vary widely but the most common are sandy and clay soils. They both come with their own challenges: Sandy Soil: Water drains too quickly and plants don’t have enough time to absorb moisture and nutrients (Sandy soils are common in East Anglia, Cornwall, Devon, Dorset, and parts of Scotland)  Clay Soil: Holds too much water which can lead to root rot and lack of oxygen. When dry, it is hard, compact and difficult for roots to grow. (Clay soil is common in Kent, Sussex, and parts of the North West)  Rocky Soil: Shallow, nutrient-poor soil that makes it difficult for plants to establish strong roots. Suitable for deep-rooted species. Often found in cliffside and exposed coastal areas (Scotland, Wales, Cornwall, Devon, and Northern Ireland). Drought & Heavy Rains Summer drought can severely stress the plants, especially in sandy and chalky areas. At the same time, coastal climates often bring heavy winter rains that can lead to waterlogging and soil erosion. This dramatic change between very dry and very wet conditions makes plants with strong and deep roots most suitable for coastal gardens. The Best Trees and Shrubs for Coastal Gardens UK Coastal gardens need resilient trees and shrubs that can flourish despite harsh winds, salt spray, and sandy soils and also add beauty and structure to the landscape. Here is our carefully curated selection of the best coastal plants for UK gardens, designed to help you create a beautiful seaside haven. Scots Pine (Pinus sylvestris) Why: A tough, wind-resistant evergreen tree that makes an excellent shelter for exposed coastal gardens. It thrives in poor soils and adapts to different moisture levels. Maritime Pine, Monterey Pine, and Corsican Pine are also great choices for coastal regions. Ideal for: Western and northern coastal areas (Wales, Cumbria, Scotland), where high rainfall and acidic soils are common.  Aspen (Populus tremula) Why: A UK-native, highly wind-resistant tree that thrives in wet coastal soils and tolerates salty conditions. Its broad, spreading form makes it ideal for shelterbelts in open coastal landscapes. Some other poplars, such as Lombardy, White, or Grey Poplar are also excellent for coastal areas. Best for: Western and northern coastal regions, where high rainfall and occasional waterlogging occur. Perfect for stabilising damp soils and creating wind protection. Tamarisk (Tamarix ramosissima) Why: An excellent coastal plant that thrives in salty, sandy soils and can handle intense sun and drought. Other Tamarisk species, like Saltcedar (Tamarix ramosissima), French Tamarisk (Tamarix gallica), and evergreen Athel Tree (Tamarix aphylla) are also very adaptable to coastal conditions. Best for: Eastern and south-eastern coasts (Norfolk, Suffolk, Kent), where drier conditions and free-draining soils are common. Common Alder (Alnus glutinosa) Why: An exceptionally tough tree that thrives in wet soils, making it perfect for areas prone to winter flooding. It has moderate drought and salt tolerance, therefore, does not thrive in very salty or dry soils. Grey Alder (Alnus incana) is less tolerant to salt but more adaptable to drought.  Best for: Western and northern coasts, where heavy rainfall and boggy conditions are common. Field Maple (Acer campestre) Why: A UK native, salt-tolerant and moderately wind-resistant tree. Its beautiful and dense foliage makes it a great choice for hedgerows and shelterbelts in coastal gardens. A few other maple species can thrive in coastal areas, too, such as Norway Maple (Acer platanoides) and Sycamore (Acer pseudoplatanus) Best for: All UK coastal regions, particularly those needing a compact, hardy tree for mixed plantings. Elaeagnus x ebbingei (Oleaster) Why: One of the toughest and most widely planted coastal Elaeagnus varieties. It is salt-tolerant, wind-resistant, thrives in poor soils and tolerates drought. A deciduous variety Elaeagnus angustifolia (Russian Olive) is also highly drought and salt. Best for: All UK coastal regions, particularly eastern and southern gardens, where it tolerates drier conditions and provides dense wind protection.tolerant. Griselinia (Griselinia littoralis) Why: Fast-growing, evergreen shrub with glossy leaves, excellent for hedges or windbreaks in exposed coastal locations. It thrives in mild, damp conditions and is resistant to salt spray. Griselinia lucida (Shiny Broadleaf) is moderately salt and wind-tolerant and can be used in sheltered coastal gardens.  Best for: Mild western and southern coastal regions (Cornwall, Devon, Wales), where it will enjoy moderate winters and high rainfall. Butterfly Bush (Buddleja davidii)  Why: A fast-growing, deciduous shrub known for its fragrant flower spikes that attract butterflies and bees. It is highly adaptable - tolerates wind, salt spray, and a range of soil types, though it prefers well-drained conditions. It is not as salt-tolerant as Griselinia or Elaeagnus, but it can thrive in moderate coastal exposure. Best for: Southern and eastern coastal gardens, where it benefits from drier soils and full sun. Our selections for coastal trees and shrubs offer the perfect balance of beauty and resilience. With the right mix and proper maintenance, you will create a beautiful and resilient landscape that you can enjoy all year round.

Plant windbreaks using salt-tolerant hedging's like Griselinia littoralis, Elaeagnus × ebbingei, or Tamarisk to filter the salty winds before they reach more delicate plants. Apply a thick layer of mulch to prevent salt from accumulating in the soil. Also, rinse leaves with fresh water after storms to prevent salt damage. How do I improve sandy coastal soil for planting trees and shrubs?  To improve sandy coastal soil for trees and shrubs, mix in compost, well-rotted manure, or seaweed to add nutrients and retain moisture. Mulch can reduce water loss, while grit-free topsoil or clay improves structure. Using mycorrhizal fungi supports strong root growth, and choosing drought-tolerant plants ensures success. Do I need to water coastal garden plants regularly? Coastal garden plants generally need less frequent watering, as many are drought-tolerant and adapted to sandy, well-drained soils. However, young plants, newly planted trees, and shrubs will need regular watering until established, especially during dry or windy conditions. How do I plant trees and shrubs in exposed coastal areas? Start by positioning hardy, wind-resistant species like Griselinia, Elaeagnus, or Tamarisk as a natural windbreak along the garden’s windward side to shield more delicate plants. Plant trees in groups rather than alone, as this helps reduce wind pressure and creates a sheltered microclimate. Place salt-sensitive plants closer to buildings, walls, or taller hedges for protection.

How to Choose the Best Screening Tree for Your Garden

by Arundel Arboretum on Jan 15, 2025
Our standard 1.8-metre fences are great for marking boundaries, but do very little when it comes to creating true privacy. This is a common challenge for many homeowners, especially in new-build houses where gardens often feel bare and exposed. Fortunately, there’s a simple, stylish, and natural solution for this problem - screening trees. What Are Screening Trees? Screening trees are specially selected trees planted to create a natural barrier and enhance your garden privacy. They grow taller than a standard fence and can extend the height of your garden screen by 5-8 metres. Along with privacy, screening trees bring aesthetic benefits like lush greenery, refreshing shade, and seasonal beauty. This allows you to enjoy your outdoor space in peace, free from unwanted views. Types of Screening Trees: Pros & Cons You are thinking of improving your garden’s privacy by planting screening trees but don’t know where to start? The first step is to consider the types and sizes of screening trees available. You can typically choose between two types: evergreen and deciduous. Each has its own pros and cons so it’s up to you to decide which type is better for your garden. Let’s take a closer look at both options.   Evergreen Screening Trees PROS: Privacy all year round: Evergreen foliage does not change throughout the year so evergreen trees will provide constant privacy, no matter the season. Less noise: Beside blocking unwanted views, the density of evergreen foliage can also reduce the noise from your neighbours or traffic. Wind protection: Evergreen trees can also serve as a natural shield against harsh winds, making your garden cosy even on windy days. Low maintenance: If you don’t have much time for your garden and need low-maintenance screening trees, evergreens may be a good choice since they require minimal care. CONS: No seasonal change: Evergreen trees stay the same throughout the year so they lack the seasonal variety of deciduous trees. Slower growth: Due to their slower growth, it may take longer to achieve the desired height. Higher risk of pests: Their dense foliage can harbour insects, which makes them more susceptible to pests. More snow damage: They can also be more vulnerable to snow damage, as the weight of snow can break their branches. Tend to be more expensive: Evergreen trees tend to be more expensive, especially mature specimens or specific varieties. Deciduous Screening Trees PROS: Attractive seasonal changes: What makes deciduous trees truly beautiful is their ability to change throughout the seasons. They usually offer lovely spring blossoms, vibrant summer foliage, and attractive autumn colours. Faster growth: Deciduous trees tend to grow faster than evergreens. Therefore, if you need fast-growing screening trees, deciduous may be a better solution. Lower risk of pests: Deciduous trees have fewer pest problems compared to evergreens. Less snow damage: They are also less likely to suffer from snow damage. More affordable: More mature deciduous trees are often cheaper compared to their evergreen counterparts.  CONS: Less privacy in winter: Deciduous trees shed their leaves, leaving your garden more exposed during winter. They are better suited as seasonal privacy trees. Longer wait for full privacy: Deciduous trees also need more time to grow dense enough to provide full privacy. Sometimes bare spots in their foliage may appear. More maintenance: They need regular pruning and clearing of fallen leaves which makes them harder to maintain than evergreens. Higher risk of diseases: Deciduous trees are also more susceptible to certain diseases, especially fungal infections. Vulnerable to late frosts: Late frosts in spring can damage new growth and impact their development and beauty. Choosing the Right Size of Screening Trees for Privacy Screening trees usually come as Full Standard (Std) and Three-Quarter Standard (3/4 Std). Before you choose, it’s important to understand what these terms mean. Different tree standards refer to the height of the clear stem which is followed by the canopy at the top. Full-Standard Screening Trees Height: Full-standard trees have a single straight trunk, clear of branches up to at least 1,8m and a broad, spreading canopy above. Benefits: Perfect for adding height above a standard fence. The canopy creates a natural barrier while the space below remains open and uncluttered. Best use: They are a great choice for larger gardens, standard fences, paths, or driveways. Full-standard trees create a formal and structured look and keep the ground level open and visible. Things to consider: Full standard trees need more vertical space to thrive and slightly more time to establish a dense canopy. Three-Quarter Standard Screening Trees Height: Three-quarter standard trees have a single clear stem or trunk with a neat canopy above. The trunk is usually between 1.5 and 1.8 metres high. The canopy begins at around 3/4 of the tree's overall height making it closer to the ground. It is also more compact and dense than canopy in a standard tree. Benefits: Great for adding privacy at eye level which makes them a good choice for seating areas or patios. The space below the canopy stays clear and airy. Best Use: Perfect for smaller gardens and urban spaces where you want privacy but not overly high trees, or where full-standard trees feel out of proportion. Things to consider: Three-quarter standard trees may not be the best choice for screening in large gardens. They can appear out of proportion or be less effective in creating privacy. Best Evergreen Screening Trees for Garden Privacy Here are our top evergreen trees that offer excellent garden screening solutions. Hoheria Snow White Fast growth, attractive evergreen foliage, and masses of elegant, white flowers blooming in summer make Hoheria Snow White a great choice for screening. This tree prefers sheltered positions and may struggle in windy and exposed areas common in coastal or hilly areas of the UK. Photinia Red Robin Photinia is adaptable, hardy, and easy to grow. It is also very attractive with its glossy dark green leaves and bright red new growth in spring. This splash of colour is rare for evergreen screening trees. Photinia Red Robin is not needy but requires occasional pruning to maintain shape. Although it thrives in most UK climates, young plants should be protected in places with severe winters. Ligustrum ovalifolium (Privet)   If you need thick and compact screening trees that grow fast, Ligustrum ovalifolium is the perfect choice. It has very dense foliage but requires regular trimming. Harsh winters may cause it to lose some leaves and diminish its overall appearance. Ligustrum japonicum (Japanese Privet) This variety of Ligustrum is known for glossier leaves, more compact growth, and the ability to thrive in partial shade. Less cold-hardy than other privets, Ligustrum japonicum can struggle in harsh UK winters. It is better suited for milder regions of the UK. It is also slower growing than other privets. Ilex Nellie R. Stevens (Holly) Dense and hardy, Ilex or Holly can provide a very resilient and thick privacy screen with attractive, bright red winter berries. It thrives in UK gardens but grows slowly, so it may take time to establish as a privacy screen.   Magnolia Grandiflora Evergreen magnolia is well known for stunning, fragrant flowers and large glossy leaves. It combines beauty and function and makes a great screening tree. Magnolia prefers warmer, sheltered parts of the UK. It doesn’t like exposed or frosty conditions. Prunus Lusitanica (Portuguese Laurel) Portuguese Laurel is a dense, hardy, and fast-growing evergreen tree with glossy foliage. It makes an excellent screening tree and grows well in most UK regions. If you don’t want it to grow too wide, it needs regular pruning. Prunus laurocerasus Novita Novita is a robust, adaptable, and fast-growing variety of Cherry Laurel. Its dense foliage creates thick and reliable privacy screens. Since it needs room to thrive, it is ideal for larger spaces. Camellia Japonica Camellia Japonica offers glossy evergreen leaves and beautiful flowers from late winter to spring. It is both practical and decorative. However, it is not as adaptable as some other screening trees. It needs acidic soils and sheltered positions, as well as some extra care to thrive. Camellia Sasanqua This variety of Camellia is compact and elegant. Its fragrant autumn flowers are a beautiful addition to its dense evergreen foliage. Keep in mind that it may struggle in harsh frost and exposed positions. Best Deciduous Screening Trees for Garden Privacy Now, let’s explore the best deciduous trees for privacy that will create perfect natural screening in your garden. Liquidambar Gumball Liquidambar Gumball offers stunning and vibrant autumn foliage in shades of yellow, orange, and red. It is very attractive but grows more slowly than other screening trees. It needs full sun to show its vibrant autumn colours at their best. Liquidambar Worplesdon Liquidambar Worplesdon is known for its spectacular autumn colours and tall upright growth. It is an excellent choice for larger gardens because it requires plenty of space to grow. Not so suitable for small or urban UK gardens. Pyrus calleryana Chanticleer (Ornamental Pear) This is a lovely screening tree, both functional and decorative. It has beautiful spring blossoms and dense summer foliage. It’s a fast grower and can provide garden privacy quickly, but may need regular pruning to prevent it from becoming too tall. Acer Rubrum Redpointe With Acer Rubrum, you will enjoy symmetrical, upright growth habit and vibrant red leaves in autumn. It prefers moist soil and may need additional watering in drier climates. It is ideal for wetter regions of the UK. Carpinus betulus (European Hornbeam) Cold-hardiness and dense foliage, golden-yellow in autumn, make Carpinus betulus an excellent screening tree. It’s highly adaptable and thrives in various soils. It is slower to establish compared to some other trees, but once mature, it will provide a strong and reliable natural garden screen. European Hornbeam is highly adaptable and thrives in most UK climates. Fagus sylvatica (European Beech) European Beech, with its dense foliage that turns coppery-brown in autumn and remains on the tree throughout winter, is an excellent choice for screening. Bear in mind that it can grow quite large if not regularly maintained. Crab Apple Trees Lovely spring blossoms and colourful fruit of the Crab Apple Tree will add real charm to your garden along with privacy. The downside of this screening tree is fruit drop that may require occasional clean-up. They thrive in most UK soils but may need good drainage to avoid root issues. Cherry Blossom Trees In spring, Cherry Blossom tree bursts with breath-taking, white and pink flowers, and in summer, offers dense foliage for seasonal privacy. It blooms best in sunny, sheltered spots, which can be harder to find in windy or exposed UK regions. It may take longer for Crab Apple to provide full privacy because of its moderate growth. Also keep in mind that the bloom period is very short. Screening trees are a fantastic way to add privacy and beauty to your garden. With so many lovely and functional options to choose from, there must be a perfect screening tree for every space. Start exploring your options and take the first step toward transforming your garden into a peaceful retreat!

How to Prune a Young Apple Tree?

by Arundel Arboretum on Mar 27, 2024
Your young apple tree is a story waiting to unfold, with you as a guide nurturing its growth and helping it reveal its full potential. Pruning is just a step in this transformative journey, setting the stage for a fruitful “happily ever after”. Here are some helpful tips for mastering the art of pruning, ensuring your apple tree grows strong and bears the perfect fruit. Start Pruning at Planting  Why prune new trees? It's a perfectly reasonable question to ask, but there is a valid reason to start pruning at the time of planting.  When you welcome a young tree into your garden, careful and thoughtful trimming will prepare it for a lifetime of lush growth. While many gardeners, even experienced ones, will say that pruning newly planted trees compensates the root loss or helps the tree survive the planting, the latest research shows that is not quite true.    Pruning cannot compensate for root loss and doesn’t help the tree in overcoming the shock of transplantation. The more leaves you leave on the tree, the happier and healthier roots will be in their new home. As we already know, leaves turn sunlight into energy, and that energy fuels the root growth and helps it get over the shock of moving.  Then, why pruning when planting? Pruning at the time of planting is for structure only. It should be done to establish the best possible structure to help it grow strong and beautiful in the future.  How to Prune a Young Apple Tree? The first pruning should be done immediately after planting. The critical question of when to prune a new apple tree is, therefore, closely connected to its planting period. The best time to plant a new apple tree is from late November to early March, while the tree is still dormant. That’s also the time when you should do the first pruning. Young apple trees are sold in three main forms. Understanding these forms of young apple trees is crucial for effective pruning. These three main forms of a young apple tree available for sale are: Unfeathered Maiden Feathered Maiden Two-Year-Old Tree The main goal of pruning a young apple tree is to form a strong central leader or a trunk by removing branches that are growing upright and fighting for dominance with the leader or are too closely spaced. Also removing branches that are damaged or broken can prevent potential future issues. Unfeathered Maiden (A Single-Stem 1-Year-Old Apple Tree) An unfeathered maiden is a 1-year-old tree with a single stem or trunk and no side shoots. The main goal of pruning 1-year-old apple trees is to: Encourage them to branch out Make them stronger How to Do It: Cut the top of the stem just above the bud Ensure there are 3 or 4 healthy buds below Make the cut about: 75cm from the ground for standard and half-standard trees 60cm from the ground for a tree on a dwarfing M27 rootstock This approach encourages the tree to grow lateral branches. The healthy development of these branches is essential for a strong and productive structure. Be aware that you are not just cutting, but guiding your tree towards fulfilling its full potential. Feathered Maiden (1-Year-Old Apple Tree with Side Shoots) A feathered maiden is a 1-year-old apple tree with several side shoots on the main stem. The key goal of pruning feathered maiden is to: Select well-placed branches Create a balanced, open tree structure Shape the tree for future growth How to Do It:  Examine the tree’s structure Identify the central trunk, which is the main upward branch Remove any shoots that compete with it Choose 3-5 strong, well-spaced, outgrowing branches They should be evenly distributed around the trunk Ideally, angled 45 to 60 degrees from the trunk Cut the top of the main branch (trunk) just above the highest side shoot Shorten the branches you previously selected by half to two-thirds Cut them just above an outward-facing bud Remove any side shoots below them Remove damaged or broken branches By following these steps, your feathered maiden apple tree will be on its way to becoming strong and well-shaped, ready to grow and bear fruit for years to come. 2-Year-Old Apple Tree (Newly Planted or In Its Second Year) Pruning a Newly Planted 2-Year-Old Apple Tree (Pre-Trained by the Grower) If your newly bought apple tree is 2 years old, it is probably partly pre-trained. It has likely already started to form a basic structure, but it can still benefit from formative pruning. Pruning 2-year-old apple trees is similar to pruning feathered maiden trees. The only difference is that with a 2-year-old tree, the main stem or trunk is most probably cut back by the grower but the tree may have sprouted a replacement upright shoot. You need to cut it back just above the highest side shoot. Pruning the Second Year After Maiden (Two Years in Your Garden) Pruning your apple tree in its second year in your garden is very important for its robust, healthy growth and abundant fruit production. The goal is to: Develop a strong and well-structured framework of branches Make the tree capable of bearing the weight of the fruit Pruning should be done late in winter or early in spring, before the new growth emerges. Here is a simple guide on how to prune a young apple tree in winter. Hot to Do It: Examine the tree’s structure Remove competing branches to maintain a single, strong, central leader Choose 8 to 10 side shoots evenly spaced around the trunk To establish the permanent branching structure Remove the branches that are growing vertically, too close, crossing, or rubbing against each other Remove shoots that main branches do not need Shorten the branches by half to two-thirds Cut just above the outward-facing bud Remove suckers (growing from the base of the trunk) and water sprouts (upright shoots on branches) Remove diseased, dead, or damaged branches Keep the centre of the crown open Pruning in the second year is important for strengthening the structure that was established in the first year. Thoughtful shaping of the tree will be highly beneficial for its strength and fruit production. Pruning 3-Year-Old Apple Trees After 3 years, your apple tree is already well structured and pruning is a means of refining its shape and preparing it for fruit production. In this stage, the goal of pruning is to: Shape and refine the tree’s structure Improve air and light circulation throughout the canopy Crucial for the quality and quantity of harvest Encourage the growth of fruiting spurs How to Do It: Cut back the last growth by a quarter Cut the branches that are becoming disproportionately long Keep the side-shoots on the main branches These branches will develop fruiting spurts and bear fruit Remove them only if: They grow into the crown’s centre Become too crowded Rub against each other Remove suckers and water sprouts By the third year, pruning your apple tree is completing the setting of the stage for healthy and abundant fruit production. Pruning Apple Trees for Fruit Production The proper pruning of apple trees is essential for maximizing healthy fruit production. The goal of this kind of pruning is to: Remove dead, diseased, or damaged branches Thin canopy to improve airflow and light exposure Maintain a balance between vegetative growth and reproductive growth Prevent the tree from producing too many small, poor-quality fruit Pruning at this stage ensures that the apple tree is getting enough air and sun and preventing its energy from being spent on leaf growth instead of fruit production. It is important to know that apple trees produce fruit on spurs – short, stubby branches. They must not be overcrowded because they need a lot of sun and fresh air. How to Do It: Remove entire branches if the canopy gets too crowded to open it up Remove the branches that compete for nutrients and sunlight Shorten branches by cutting them back to a bud Make sure spurs are not overcrowded After pruning, water the tree and mulch to retain the soil moisture If you set the stage correctly and make sure every fruit gets its share of sun and fresh air, you can happily expect a bountiful and delicious harvest. Thorough care in the first few years will reward you with crisp, tasty apples, making every bit of your effort worthwhile. Pruning Young Apple Tree Aftercare After the pruning is done, there are some things to do to ensure good aftercare and prevent various problems. First of all, make sure the tree receives enough water and mulch it to keep the soil moist. Based on the soil test, fertilize the soil if needed. As for the wound care, it is better to let it heal naturally. Monitor to see any signs of pests or disease on time and react adequately. Protect the tree if it’s in a windy location or too much exposed to the sun. Support the tree with a stake if its structure is significantly altered, especially in windy locations. By following these steps, you will help your tree easily recover from pruning and prepare for successful growth and abundant yield. Be patient and gentle and your young apple tree will thrive and reward you with its beautiful blossoms and tasty fruit for years to come. FAQ What are the most common mistakes when pruning an apple tree? When it comes to pruning a young apple tree, here are some most common mistakes you should avoid: Not pruning every year Pruning without a plan Pruning too early in winter Over-pruning Not thinning out the canopy Should I take off the fruit of a young apple tree? Yes, all the fruit in the first growing year should be removed from the tree, as well as half of the fruit the next year. For the first 2 years, it is best to direct the tree’s energy into growing roots. After that, remove only damaged fruit or thin out if the crops get too heavy for the tree. Too much crop can end with too small fruit of a lower quality. Is my new apple tree dying? New trees often experience transplant shock and struggle to establish their roots. If it doesn’t have enough room for its roots or is not watered properly, it may show signs of dying. Here is how to tell if your newly planted apple tree needs help: Bend a branch If it breaks easily, the tree is dying or is already dead Gently scratch the bark with your fingernail If a layer beneath is moist and green, your tree is alive How do you save a young apple tree? If your newly planted apple tree is experiencing stress, you can try some of these things to help it: Make sure it gets enough water At least 15-20 litres of water per week Add a layer of mulch to keep the soil moist Keep it around 10 to 15 cm away from the trunk Check the pH and nutrient levels of the soil Apple trees prefer a pH range of 6.0 to 7.0. Prune for structure to improve air circulation and enable more sunlight Remove all damaged, diseased, or dead branches Based on the soil test, apply fertilizer Don’t over-fertilize because the excessive growth can cause other problems

How to Prune Magnolia Trees?

by Arundel Arboretum on Mar 06, 2024
Magnolia trees are easy to maintain and rarely require pruning. When they do, it’s usually to remove dead or damaged branches. So with magnolia in your garden, you can enjoy the exquisite beauty of nature without too much hassle. Is It Necessary to Prune Magnolia Trees? Unlike the trees that require regular pruning to thrive or others that can tolerate severe trimming, magnolia is a low-maintenance plant that generally doesn’t like pruning. So before you reach for the pruning shears, pause and rethink if your magnolia tree really needs this intervention. How to Prune a Mature Magnolia Tree? When pruning a mature magnolia tree, be sure to prune it lightly. Magnolias don’t like excessive pruning and don’t respond well to it. Mature magnolia trees should be pruned only if necessary, to remove dead or diseased branches, or to correct the shape and structure of the tree.If the tree is old, diseased, or stressed, excessive pruning can cause further harm. Neglected trees could require significant corrective pruning which can be challenging and may need professional assistance. When to Prune Magnolia Trees? For magnolia trees, timing is everything. When is the perfect time to prune them? Basically, from late spring to early autumn.Every gardener knows that the ideal pruning time for most trees is late winter or early spring. In this period, trees are still dormant which reduces the stress of pruning and minimizes sap loss. However, magnolia trees are a little bit different. They are resilient beauties with their own set of rules when it comes to pruning. Understanding and accepting these rules will make your magnolia flourish and keep revealing its stunning blooms every year. Why Not Pruning Magnolia in Late Winter? Magnolia’s unique pruning schedule is based on several factors: Blooming Cycles Beautiful, often large, fragrant, tulip-like, magnolia flowers are the main feature of this tree. Their blooming cycle is of utmost importance for choosing the best time to prune. Magnolias generally bloom in early spring before the leaves emerge. If you prune them in late winter or early spring, you risk accidentally cutting off the buds formed in the previous year. You may reduce or even destroy the flowering for that season and deprive yourself of enjoying the beautiful magnolia blossoms. The Best Season for Healing Magnolias may need time to heal from pruning cuts. That’s why it’s crucial to prune them at a time when they can heal quickly.Deciduous magnolias are usually pruned in late summer which allows them to heal before the dormancy period.Evergreen magnolias are usually pruned in late spring during the active growth period which allows the tree to recover quickly and further develop its lush evergreen foliage. Disease Prevention Many fungal and bacterial diseases that attack magnolia trees occur and spread more easily in wet conditions, which are typical for late winter and early spring. By pruning your magnolia in dry periods, from late spring to late summer, you minimize the risk of exposing fresh cuts to pathogens when they are most active. What Are the Signs Your Magnolia May Need Pruning? The main signs that your magnolia tree needs pruning are: Dead or dry branches Branches with signs of disease Damaged branches Suckers (shoots from the base) Water shoots (shoots from branches) Branches that cross over each other Branches that rub against each other Too dense canopy Overgrown canopy How to Prune a Magnolia Tree: A Simple Step-By-Step Guide Keeping your magnolia in top shape is not hard. After all, magnolia is not a needy plant and doesn’t require much care. Follow this simple step-by-step guide to pruning to help your magnolia tree thrive. General rules for keeping your magnolia happy and well-maintained are: Prune in adequate time, when the magnolia finishes its blooming Before pruning, identify dead, damaged, diseased, crossing or rubbing branches Remove dead, damaged, and diseased branches Remove branches that are crossing or rubbing each other Remove suckers and water shoots If a canopy is too dense blocking light and air circulation, thin it out If needed, lightly prune to maintain the natural shape Do not remove more than 15% of the canopy per year Use clean and sharp tools Make clean cuts just above the bud or where branches join Angle the cut to prevent water from collecting After pruning, water the tree and mulch it to maintain moisture How to Prune Deciduous Magnolias The most important thing about pruning a deciduous magnolia tree is timing. The best time to prune is between summer and early autumn after magnolias finish blooming. Make sure you don’t accidentally remove buds for the next year’s bloom. In young deciduous magnolia plants, prune any weak growth or branches that ruin their natural shape. Mature plants often grow vertical shoots, known as water shoots. They should be cut back to the trunk or branch. How to Prune Evergreen Magnolias Evergreen magnolias can tolerate more pruning than deciduous ones, but excessive trimming can be stressful to the plant and affects its flowering. Young evergreen magnolia trees usually do not need pruning. Evergreen magnolias can be pruned for size-control and landscaping purposes which is less common for a deciduous variety. The ideal timing for pruning evergreen magnolias is late spring or early summer when there is no more danger of late frosts. How to Prune Wall-Trained Magnolias Magnolias can be easily grown against the wall or a trellis. To do it properly, it’s important to understand their natural growth habit. This understanding should guide all pruning decisions When pruning a wall-trained magnolia, focus on maintaining the desired shape against the support structure. Cut off stems facing towards the wall and shorten those growing away from the wall to one or two leaves. All the branches should be tied to the wall or trellis and the ones that cannot be easily tied should be pruned. The goal is to keep the plant flat. Use soft ties or garden twines to secure the branches. Be careful not to damage the bark. What Are the Common Pruning Mistakes with Magnolia Trees? To ensure a stunning and robust magnolia tree in your garden, keep away from things that can seriously damage it. Follow these simple tips to avoid the most common mistakes: Prune at the right time of the year Avoid shocking the tree with over-pruning Do not cut healthy growth Know where the buds are to avoid cutting them Maintain the tree’s natural form Never top the tree to reduce the height Prune young magnolias very lightly FAQ Why isn't my magnolia tree flowering? Magnolia trees may fail to flower due to many reasons. Here are some of the common ones: Magnolia flower buds are formed in autumn, preparing for blooming next spring. Pruning in autumn or winter can cut off the flower buds causing the tree not to flower. Some magnolia flower buds are frost-sensitive and may die due to severe cold. Flower buds can also perish because of the insect called thrip. Magnolias like moist, well-drained soils. If the soil around the dries out too much in summer, it may avoid producing flower buds to stay alive. Should I deadhead a magnolia tree? Deadheading or removing spent flowers is a common practice for many flowering plants as it stimulates new blooms. However, magnolia trees do not require deadheading nor it is advised as a regular care. They naturally shed their spent blooms. Should I cut brown leaves off the magnolia? Yes, removing brown leaves from the magnolia tree is highly recommended. By pruning dead foliage, the tree can focus its energy and resources on healthy growth. How often should magnolia be pruned? Magnolia tree requires minimal pruning. It doesn’t have to be pruned every year, but every couple of years, dead, diseased, and damaged branches should be removed to maintain the natural shape.
How to care for a plum tree for optimal fruiting results?

How to care for a plum tree for optimal fruiting results?

by Arundel Arboretum on Jan 17, 2024
Caring for a plum tree to achieve optimal fruiting involves several key steps: selecting the right variety, planting, watering, fertilization, pruning, pest and disease management, and proper harvesting. Each of these steps contributes to the health and productivity of the tree. 1. Selecting the Right Variety The first step in successful plum tree care is selecting a variety that suits your climate and soil type. Plum trees can be divided into two main types: European plums, which are more suited to cooler climates, and Japanese plums, which prefer slightly warmer conditions. Research local varieties and consult with a nursery to choose a type that will thrive in your specific environment. 2. Planting Plant plum trees during the dormant season, preferably in late winter or early spring. Choose a sunny spot with well-draining soil. Planting in a location that receives at least six hours of sunlight each day is crucial for fruit production. Ensure the root ball is level with the ground surface and water thoroughly after planting. 3. Watering Regular watering is essential, especially during the first few years and in dry periods. Over-watering can lead to root rot, while under-watering can stress the tree and reduce fruiting. A good rule of thumb is to water deeply once a week, adjusting based on rainfall and soil conditions. 4. Fertilization Fertilize your plum tree in early spring before new growth begins. Use a balanced fertilizer or one formulated specifically for fruit trees. Over-fertilization can lead to excessive foliage growth at the expense of fruit production, so follow the recommended rates. 5. Pruning Prune plum trees annually to maintain their shape, remove dead or diseased wood, and encourage fruit production. Pruning is best done in late winter or early spring. The goal is to create an open canopy that allows light and air to reach all parts of the tree, which helps in reducing disease risk and promoting even ripening of fruit. 6. Pest and Disease Management Regularly inspect your plum tree for signs of pests and diseases. Common issues include aphids, plum curculio, and fungal diseases like black knot. Implement appropriate control measures promptly, which may include the use of insecticides, fungicides, or organic alternatives. 7. Harvesting Harvesting at the right time is crucial for the best quality fruit. Plums are ready to harvest when they come off the tree easily with a slight twist and have full color. Harvesting typically occurs in late summer or early fall, depending on the variety. Conclusion Caring for a plum tree requires attention to detail and an understanding of the tree’s needs throughout the year. By following these steps and monitoring the tree's health regularly, you can enjoy a bountiful harvest of delicious plums for many years. Remember, patience and consistent care are key to cultivating a healthy and productive plum tree.  Arundel Arboretum has a very wide selection of Plum Tree available at the nursery and for delivery, check out our stock.

How to trim a cherry tree?

by Arundel Arboretum on Jan 14, 2024
Trimming a cherry fruit tree is an essential part of its maintenance and health. The process, known as pruning, not only influences the tree’s aesthetic appeal but also its fruit production and overall health. Pruning should be done during the dormant season, typically in late winter or early spring, to minimize disease risk and to allow the tree to heal before the growing season begins. 1. Understanding the Tree’s Growth Pattern: Cherry trees grow in two forms: sweet (Prunus avium) and sour (Prunus cerasus). Each has a slightly different growth habit and pruning requirements. Sweet cherry trees, often larger, are typically pruned into a vase shape to allow sunlight and air circulation. Sour cherry trees, more compact, are generally pruned into a central leader system, where a main vertical branch is the focal point. 2. Tools and Safety: Before starting, ensure you have the right tools. Use sharp, clean pruning shears for small branches and a pruning saw for larger limbs. Safety is paramount; wear gloves and safety goggles to protect from sharp branches and debris. 3. Basic Pruning Steps: Remove Dead or Diseased Wood: First, cut away any dead, dying, or diseased branches to prevent the spread of decay and to improve air circulation. Thin Out Overcrowded Areas: Identify areas where branches are overcrowded. Removing some of these will improve light penetration and air flow, essential for healthy fruit development. Cut Back Old Wood: Older wood often produces less fruit. Prune some of this back to promote growth of new fruiting wood. Shape the Tree: Maintain the overall shape of your tree – vase-shaped for sweet cherries and central leader for sour cherries. This step is important for the tree’s structural integrity and aesthetic. 4. Pruning Young vs. Mature Trees: Young cherry trees (1-3 years) should be pruned lightly to establish the desired shape. Mature trees require more aggressive pruning to maintain shape, encourage fruit production, and remove any unproductive wood. 5. Timing and Frequency: Prune cherry trees annually to maintain their health and productivity. The best time to prune is late winter or early spring before the sap starts to flow and the buds swell. 6. Aftercare: After pruning, ensure the tree is well-watered, especially if the weather is dry. Mulching around the base can help retain moisture and provide nutrients. 7. Monitoring and Maintenance: Regularly inspect your cherry tree for signs of disease or pest infestation. Prompt action can prevent most issues from becoming serious. In conclusion, proper pruning is crucial for the health and productivity of cherry trees. By understanding the tree’s growth pattern, using the right tools, and following the basic steps of pruning, you can ensure your cherry tree remains healthy, aesthetically pleasing, and fruitful for many years. Regular maintenance and monitoring will also contribute to the tree's overall wellbeing.

When to plant magnolia trees?

by Arundel Arboretum on Jan 11, 2024
Planting a deciduous Magnolia tree in the UK requires careful consideration of several factors to ensure successful growth and blooming. These factors include the right time of year for planting, soil conditions, and ongoing care. The ideal time to plant a deciduous Magnolia tree in the UK is during the dormant season, which typically falls between late autumn and early spring. Planting during this period minimizes stress on the tree, as it is not actively growing and can establish roots in the new location before the growing season begins. Late autumn planting is particularly beneficial because the soil is still warm, encouraging root growth. However, if the soil is waterlogged or frozen, it's best to wait until conditions improve.  Its worth mentioning that pot grown or pot established trees can be planted all year round, as long as you provide plenty of water during the dry season. When planting potted tree make sure your hole is twice the size of the pot and backfilled with good quality compost. Soil preparation is crucial for Magnolias. They prefer a neutral to slightly acidic, well-drained soil rich in organic matter. Before planting, incorporate plenty of well-rotted garden compost or manure into the planting hole and surrounding area. This will improve soil structure and fertility, providing a good environment for root growth. When selecting a planting site, consider the tree's eventual size and shape. Magnolias need space to grow both above and below ground. Choose a sheltered spot to protect the tree from strong winds, which can damage the branches and flowers. A south or west-facing position is ideal as it ensures adequate sunlight, essential for the tree's growth and flower development. Planting a Magnolia tree involves carefully removing it from its pot or container, placing it in the prepared hole, and ensuring that the top of the root ball is level with the soil surface. Fill the hole with soil, gently firming it down without compacting it, and water thoroughly. A layer of mulch around the base of the tree, avoiding direct contact with the trunk, can help retain moisture and suppress weeds. After planting, regular care is necessary, especially in the first few years. This includes watering during dry spells, as young trees are particularly susceptible to drought stress. Annual mulching helps maintain soil moisture and temperature, and adding a balanced, slow-release fertilizer in spring can support healthy growth. Pruning is generally not required for young Magnolia trees, as they naturally form an attractive shape. However, if necessary, pruning should be done in mid-summer after the tree has flowered. This timing helps reduce the risk of disease and avoids cutting off next year's buds. In conclusion, the best time to plant a deciduous Magnolia tree in the UK is during the dormant season, ideally in late autumn, provided the soil conditions are favorable. Proper site selection, soil preparation, and ongoing care are vital to ensure the health and beauty of the tree. With the right attention and conditions, a Magnolia tree can become a stunning focal point in any UK garden, offering spectacular spring blooms for many years to come. At Arundel Arboretum we have hundreds of magnolia trees of different varieties available all year round at the nursery and for online purchase for delivery. Check out our range of Magnolia trees.
Screenage – Olive Trees

Screenage – Olive Trees

by Arundel Arboretum on Nov 23, 2022
We sell so many screening trees so they make a popular choice for me to talk about in the blog. At present we have the following in stock: Photinia x fraseri ‘Red Robin’, Ligustrums, Quercus ilex and Hoheria. These varieties prove to be the most popular, most likely because they are evergreen and at least one of these trees will be suitable for your ground conditions i.e. chalk or clay soils. A good screening tree that is also becoming a very popular container tree is olive. Because the olive is acclimatised to prolonged dryer conditions it is the ideal tree for not getting stressed if not watered for a month. So if you are away for a few weeks, at least you know it is unlikely to suffer too much. It is always wise to put them in the shade. Olive trees for screening are best to be shaped and this is easily done. I will always take a pair of secateurs to them once a year. Olive trees are also good for a manageable shade tree in a container. When our customers come to us for advice and ask for screening trees, we always try to establish the following information: soil type, whether the plant will be planted in a north-south-east-west facing position, how close to the sea the site is and how wet or dry the ground is. This will allow us to recommend a species that is most likely to thrive in those conditions giving it the best chance of health and growth.
Olive and Bay Tree Maintenance

Olive and Bay Tree Maintenance

by Arundel Arboretum on Nov 23, 2022
Maintenance of container grown Olive or Bay trees: To stop your tree looking tired or dying, it is wise to remove the tree from the container in November-December on a day when the root system is not frozen to stop thermal frosting of the root system. Cut away ten per cent of the root system from all around the root system. Then, using a mix of 50% good quality potting compost and 50% topsoil, mixed together well, add to the bottom of the container with a slow release fertiliser. Put the tree back into the container and fill around the sides. Doing this every year or every other year, will encourage a stronger, healthier root system. This in turn will help the tree to withstand any fungal attack at the roots, as well as the foliage. Feeding over the roots in a container should happen between March to September. We do sell the ideal fertiliser to use. Pruning the head of the tree into your desired shape can be throughout the year on that year’s growth. If pruning harder into thicker growth we would recommend leaving this until November- December. Thicker wood will bleed during the growing season. This can encourage insects that will feed from the sap. The insect could have been on a diseased tree beforehand and with an open wound, the likelihood of infection is greater. In the winter, the sap cycle is reduced massively and most insects are hibernating. Therefore, in our opinion there is less risk of infection.
The Best Trees for Screenage

The Best Trees for Screenage

by Arundel Arboretum on Nov 23, 2022
Red Robin – Photinia Fraseri Initially I would suggest Photinia fraseri ‘Red Robin’. It is normally grown as a shrub (so if you are looking for information you will find it in books about shrubs). A lot of nurseries, including ourselves, supply them as a clear stem tree (trunk from root to first branch break 150-180cm is classed as a standard). They grow 6m – 7m. It is a tree that can take hard pruning and cutting with a hedge cutter – so as tough as old boots! Can stand heavy chalk soil and exposed windy conditions. I would not use direct onto the sea, but second road back should be fine. Will grow on acidic clay soil but will not stand growing on water-logged ground. The new growth in the spring is a strong vibrant red, slowly turning green then staying green through the winter months. The leaf shed is normally March through to June. This old tired foliage will mostly be replenished. Has clusters of white flowers in the spring (stunning) followed by red to orange berries which the birds love. Portugese Laurel - 'Prunus Lusitanica' As a standard evergreen tree, it has a smaller leaf than most evergreens. The slightly darker green leaf produces cone shaped clusters of white flowers followed by green-red turning to sometimes dark purple to black berries in the autumn. The berries are not poisonous and the birds love them. A slower growing evergreen, the Portugese Laurel keeps a better shape than most and can be shaped to size. I would use it for creating a screen within the outer perimeter of a garden as the smaller foliage can be lost at the end of a garden. I would always recommend a larger leafed tree for screenage on the perimeter of the garden. Very hardy grower on chalk soils. Carolina Cherry Laurel  - 'Prunus Caroliniana' I would say this has a slightly mid to lightish-green leaf, although there are a lot of differing opinions on the true colour! The trees I have dealt with so far are a mid to light colour, not dark leaves. It will survive on poorly drained, compacted soil. It will also stand drought conditions and pollution. Again, this is an inner screenage tree because of the mid to small leaf. It has white flowers followed by black berries. The berries are not poisonous and the birds love them.

Bringing Life to your Garden – 5 Perfect Trees for Birds

by Arundel Arboretum on Nov 23, 2022
As beautiful as trees can be on their own, any garden is improved by the addition of some resident wildlife. Today we’re discussing the best trees for tempting birds into your garden… Any tree planted helps birds by providing berries or fruit to feed off in the autumn and, when in leaf, attracting insects that feed on foliage. These insects then help birds to rear their chicks, providing a food source for the chicks and the birds too. Also important for a nesting site is a thorny tree, as this will add extra protection for nesting birds against squirrels raiding their nests. A few of our favourite trees are: Amelanchier canadensis – a small, deciduous tree with green foliage, turning yellow-red and orange copper tinges in the autumn. It has masses of small white flowers normally in April, which are followed by berries. Crataegus persimilis ‘Prunifolia’ – a small tree with glossy green foliage, turning such stunning colours in the autumn. Red-orange-yellow. It has white flowers in May followed by large berries ripening late into the autumn. It is good for Fieldfares and Red Wings and is such a tough tree. A heavily thorned tree (common name Cockspur Thorn) it is an ideal nesting site. Malus ‘Evereste’ – is another small tree which has green leaves that turn mainly yellow in the autumn. The white flowers produce good crab apples into the winter. We have spent time observing Fieldfares eating the crab apples when snow is on the ground, with Thrushes and Blackbirds jostling for position! Corylus Avellana (Hazel) – All the way through the spring, summer and autumn the Long Tailed Tits feed off the insect life on the leaves. This small tree turns brilliant yellow in the autumn. Euonymous Europeaus ‘Red Cascade’ – This deciduous tree has green leaves, turning red-orange and yellow in the autumn. The white flowers develop a pink shell with an orange berry that will show itself when ripe. The birds love them.

Beat the Heat! Tips for Dry Weather

by Arundel Arboretum on Nov 23, 2022
What a dry summer – the ground is parched. It is most important to maintain the required amount of water. Keep you trees, shrubs etc. moist to dry, this will allow the water to drain through the root system so the feeler roots will chase the water to the water table. Overwatering will not make the trees or shrubs grow faster. All you will do is semi-drown or drown the root system. This will encourage the root system to rot. Everybody’s’ ground is different to how fast or slow it dries out. Therefore, if your trees or shrubs are still wet when you go to water them walk away. Do not be tempted to water. Allow the ground to start to dry before re-watering. When fertilising, fertilise around the root system – 6” the first time, then 12” then 18”. This will help to drawer the feeler roots out to the nutrient. Once a month during the first growing season should be enough. If you concentrate on developing a strong, healthy root system this will help to build strength into the tree or shrub to help them cope with windblown spore fungus that are blown in the wind from surrounding trees and shrubs, possibly miles away. They will attach themselves to the underside of the foliage, so if you do have a spray as a cure, concentrate on mainly the underside. After your trees and shrubs have built up their own immune system, they will be able to cope against a windblown spore fungus. Overwatering and under watering are a major problem.
Plant Problems: Planting Trees Too Deep

Plant Problems: Planting Trees Too Deep

by Arundel Arboretum on Nov 21, 2022
Trees that are planted too deep – we encounter this problem on a daily basis.  Most people don’t realise that this simple mistake can stop a tree from flowering, stunt the growth of the tree, or even, in extreme cases, cause it to die. So if you have a tree, shrub or climber that has not flowered or grown in the manner that you expected it to then the first step is to get the top of the root system exposed and make sure the trunk of the tree is not rotting. By covering the top of the root system you are effectively suffocating the tree, weakening the whole strength of the immune system and allowing bacterial fungi to penetrate the foliage. At this point, you will have to spray the item with a suitable fungicide concentrate – mainly spraying the underside of the foliage. It is important to focus on the underside of the foliage as this is the area most frequently exposed to spores and other irritants when winds blow through the area. These winds typically expose the underside of foliage, allowing harmful materials to attach themselves. Spraying can stop fungus travelling into the secondary bud shoot and stop the branch from dying. If you wish a nursery to identify the problem for you, always put a sample into a clear, sealed plastic bag. Nurseries will not appreciate an infected branch being waved around!

What to do in the garden in January

by Arundel Arboretum on Oct 01, 2022
As January draws to a close, it is still a quiet time as far as gardening is concerned due to the frosted layers and sprinkles of snow. However, on crisp, sunny winter days, there are plenty of small jobs to be getting on with. Paying attention to the smaller jobs now will end up being rewarding later in the year. Here are a few jobs to consider getting on with now that will save you time going into the summer months: Look into plants that can still be planted this time of year; Bare root, root ball trees and shrubs are great. Have you discovered that a particular shrub or tree is in the wrong place? As long as you can move it with a good rootball, you can move it to a more suitable position in your garden. Continue to clear away dead leaves and other debris from your garden. Weeds – they are starting to appear! Keeping them under control will save a lot of hard work and time later in the year. If you have kept an area of your garden uncut as a shelter for wildlife – keep it uncut for as long as possible especially during this cold snap where wildlife needs it most. Keep bird feeders topped up with feed and fat balls. Ensure your garden birds have a fresh supply of drinking water and defrost if frozen. Bird boxes – clean out existing bird boxes so that the birds will use them again. If you don’t currently have any bird boxes in your garden – why not consider putting one up? It’s a great winter task that will help shelter birds. They should be positioned out of prevailing winds and strong sunlight. Clean garden pots, tools, water butts and greenhouses ready for the new season, saving you the task later in the year. Check stakes and ties and other supporting systems for your trees, shrubs and climbers to ensure they are doing their job properly. Adjust or replace as necessary. Wisteria – these can be pruned now. Cut back shoots by 2-3 buds on their lateral stems. This will ensure healthy blooms come the spring. Cut back ornamental grasses – they can be cut back to within a few centimetres above the ground. Prune apple and pear trees – these are best done when the trees are still dormant. Plums\cherries\apricots – leave these alone until the summer. Pruning now will make the susceptible to Silver-Leaf infections. Here at Arundel Arboretum, one of the leading garden centres in West Sussex, our friendly team are always delighted to help and assist you with any concerns you may have about what jobs to undertake now. Why not pop in and have a look around our nursery? If you are planning to plant some new trees or shrubs this year, we have an excellent range to choose from. We shall look forward to your visit.

Fast-growing shrubs for privacy are plants often considered by our clients if they are planning to plant a hedge, particularly if it is for screenage purposes.  Hedges can also be planted to provide a definitive boundary to a property or define a certain area of a garden or act as a windbreak too. With their many benefits to your home and garden, they are worth the consideration. There are many varieties of trees and shrubs that can be considered for screenage purposes, including evergreen and deciduous. We are here to help you decide on the perfect one for you. Evergreen trees and shrubs will keep their leaves all year round – so if you are planting for privacy then this is probably the right choice for you. Deciduous plants will look good from spring-autumn but will be bare during the winter months. There are several other points to consider when purchasing your plants, which we can certainly help you with, and you will need to think about: Consider where the plants will be planted in your garden. Will there be enough room for them to spread to their optimum size? Labels on plants will often give an indication of the eventual height and spread – do not be put off by this – it is an indication and often over a 20-year period! Also, consider if you are planting for privacy\screenage you are likely to be planting near a boundary wall, fence or possibly a driveway. Root systems will grow down laterally and the bigger the plant, the bigger the root system will become. You need to ensure that the root system will not become invasive and for that reason, we would not recommend planting Bamboo, as they have a vigorous, invasive root system. Do your plants need to cope with coastal conditions for example? If so, plants to consider for these conditions include Quercus ilex and Griselinia littoralis Which way does your garden face? Will your chosen plants, for example, be able to cope with a scorching mid-day sun? What is your soil type? One way to see if your chosen plant will cope in your garden is to have a look around your local area and see what other people are growing. This is always a good indication of what grows well in your area. Visiting a specialist nursery such as Arundel Arboretum, you can be confident that you will be getting the right advice for the right plants for you. We have an excellent selection of suitable plants in stock, and five that you may like to consider include:- Hoheria sexstylosa ‘Snow White’ This is one of our favourites and we have mentioned it many times before! It has so much to offer – easy to look after, fast-growing, a dense, but delicate growth habit and beautiful white flowers in June and July. The dark green leaves are deeply serrated to give added interest. Hoheria sexstylosa ‘Snow White’ is also classed as a reasonably hardy tree and it should be able to withstand temperatures of between -5 to -10. It will grow happily in full sun, in good well-drained soil. We would advise that if your Hoheria is planted in an exposed position or is subjected to adverse weather it could get damaged. We would also recommend providing shelter in cold areas. Further information about Hoheria sexstylosa ‘Snow White’ can be found here. Prunus laurocerasus ‘Rotundifolia’ (Cherry Laurel) Prunus laurocerasus ‘Rotundifolia’ is a fast-growing evergreen shrub and an excellent choice if you do not wish to plant Leylandii. It is also an ideal plant for a shady area and is hardy. It will grow in most soils, but it does not like shallow, chalky or very wet ground. Fragrant, white flowers appear in spring and these are followed by cherry-like red fruits, which will eventually turn black. Prunus laurocerasus ‘Rotundifolia’ has an eventual height of 4-8m and a spread of 2-4m. Prunus lusitanica (Portuguese Laurel) Prunus lusitanica is an evergreen laurel, but has a smaller, neater leaf and creates more of a formal appearance than Prunus laurocerasus ‘Rotundifolia’. It has dark green leaves and produces fragrant white flowers in spring, which are followed by small, dark fruits. Prunus lusitanica will grow happily on chalky soil, but cannot withstand wet ground. It is a medium-fast growing laurel. It will grow in full sun or partial shade in a sheltered or exposed position. It has an eventual height of 12m and a spread of 8m. Photinia x fraseri ‘Red Robin’ This is another of our favourite fast-growing shrubs for privacy, again because there is so much interest to this plant! In the spring, it will produce a massive flush of bright red new foliage, which is followed by an abundance of delicate white flowers – although less so if you have regularly cut your plants back to encourage vibrant red leaf growth rather than the flowers. Laurus nobilis (Bay Laurel) Laurus nobilis is another evergreen shrub worthy of consideration. It has a dense habit and medium growth. Its aromatic leaves are useful in cooking.  Small, pale yellow flowers appear in the spring, followed by glossy black fruits in autumn. Laurus nobilis can be planted in full sun or partial shade, in a sheltered or exposed position. It has an eventual height of between 8-12m and a spread of 8m+. We have an excellent selection of fast-growing shrubs for privacy and others that you may wish to consider in stock. Why not pop in and have a look? Our knowledgeable staff will be happy to assist and advise you further on the right plants for you.

5 Specimen Plants to Choose

by Arundel Arboretum on Sep 02, 2022
Evergreen trees and shrubs are often the first choice of many of our clients today. However, there are many specimen plants that are deciduous worthy of consideration for your garden. One could argue that all plants are specimen plants as all trees and shrubs hold their own beauty – whether it’s their structure, leaf colour or texture, flowers, berries etc. Large specimen plants are often grown by themselves in order to create a greater impact and can often be found in a lawn, bed or border for a dramatic ornamental effect, unlike smaller trees and shrubs that can be planted to complement an existing planting scheme. The chosen specimen plant is often the focal point of a garden design. Which Specimen Plant to Choose? The type of tree or shrub to choose for your focal point is very much down to personal choice, and some points to consider would include:-  do you have a favourite colour? You may like to consider something that has dramatic autumn colour – for example a variety of Liquidambar.  is there a particular structure you like? An upright, Hornbeam would be a contender – either as a full tree or a standard tree is space an issue? Choosing a smaller specimen plant would be crucial, ensuring that is has enough space to spread and grow. A weeping variety of tree could be considered providing it does not get too big. At Arundel Arboretum, we have an extensive range of trees that could be planted as a specimen plant, and to help get you started, here are five trees to consider:- Liquidambar styraciflua ‘Worplesdon’ (Sweet Gum) Liquidambar styraciflua ‘Worplesdon’ is a very popular form of Liquidambar, as it is more suitable for the average garden. It is a medium sized tree with an eventual height of 12m and spread of 8m (after about 20 years). Its maple shaped leaves are green throughout the spring and summer. It has rich autumn colours of mostly orange and red. An added feature during the winter months is the cork that develops on the trunk of the tree. Liquidambar styraciflua ‘Worplesdon’ can be grown in full sun or partial shade. Carpinus betulus ‘Fastigiata’ (Upright Hornbeam) Carpinus betulus ‘Fastigiata’ is a medium sized deciduous tree. When the tree is young, the crown is narrow, but as it matures, it becomes more compact. Its green, finely serrated foliage emerges in spring and summer, before turning yellow in the autumn. Carpinus betulus ‘Fastigiata’ can be grown in full sun and partial shade, and has an eventual height of 12m after approximately 20 years. Betula pendula ‘Youngii’ (Young’s Weeping Birch) Betula pendula ‘Youngii’ is a small, deciduous tree with peeling white bark and pendulous branches, which often reach the ground to form a dome shaped tree. Yellow-brown catkins are produced in the spring. Betula pendula ‘Youngii’ can be grown in either a sheltered or exposed position, and has an eventual height and spread of 4-8m. Salix caprea ‘Pendula’ (Willow) Salix caprea ‘Pendula’ is a beautifully structured, weeping variety of willow tree. Its dramatic pendulous branches have bright yellow furry catkins during the spring, and these are very popular with the bees! Their mid-green leaves are soft grey underneath. During the winter months, the weeping branches provide a structural focal point. Salix caprea ‘Pendula’ has an eventual height and spread of approximately 2.5m, so this is an ideal choice if you have a small garden and space is of a premium. It will grow happily in full sun, in most soil types but needs a moist well-drained site. Fagus sylvatica ‘Dawyck Purple’ (Dawyck Purple) Fagus sylvatica ‘Dawyck Purple’ is an upright variety of beech. This variety is a medium-sized deciduous tree, and its young red foliage turns a striking purple during the summer. Fagus sylvatica ‘Dawyck Purple’ is a very neatly shaped, slender tree with an overall height and spread of 10m x 3m. It therefore makes an ideal choice for many gardens, especially if space is limited. They look good planted as a focal point or as an avenue of trees. In order to gain the best colour, they can be planted in full sun. It can tolerate most soil conditions, but it is best to avoid wet positions.
