Selecting the Right Cherry Fruit Tree for the UK
Growing cherry fruit trees in the UK offers the rewarding experience of harvesting your own sweet or tart fruits, coupled with the beautiful display of blossom in spring. The success of your cherry tree hinges on selecting a variety well-suited to the British climate and your garden's conditions. Factors such as pollination requirements, disease resistance, ultimate tree size, and the intended use of the fruit – whether for eating fresh, baking, or preserving – are paramount when making your choice.
- Understand pollination groups for successful fruiting.
- Choose between self-fertile and cross-pollinating varieties.
- Consider tree size: dwarf, semi-dwarf, or standard.
- Match variety to your climate and soil conditions.
- Decide on sweet (dessert) or sour (cooking) cherries.
When you're considering cherry fruit trees for your garden, the first critical decision revolves around pollination. Many cherry varieties are not self-fertile, meaning they require a compatible cherry tree planted nearby to produce fruit. This is categorised into 'Pollination Groups', typically numbered from 1 to 5. For instance, 'Lapins' is often self-fertile (Group 3), while 'Morello' (Group 3) is also self-fertile, making it a reliable choice for smaller gardens. However, if you plant a 'Stella' (Group 3) and an 'Early Rivers' (Group 3), they can pollinate each other, leading to fruit on both. Always check the specific pollination group of the varieties you are interested in. Planting two different varieties from the same pollination group, or adjacent groups, is generally recommended to ensure a good fruit set.
Sweet Cherry Varieties for UK Gardens
Sweet cherries (Prunus avium) are prized for their dessert quality, perfect for eating straight from the tree. Varieties like 'Sunburst' are popular due to their self-fertility and good disease resistance, producing large, dark red, sweet fruits. 'Lapins', another self-fertile option, is a later-ripening cherry that offers excellent flavour and is also disease-resistant. For earlier harvests, consider 'Merchant' or 'Prunus avium 'Merton Bigarreau'', both of which tend to be earlier croppers but may require a pollination partner.
Sour Cherry Varieties for Culinary Use
Sour or tart cherries (Prunus cerasus) are less commonly eaten fresh due to their acidity but are ideal for cooking, baking, jams, and liqueurs. The 'Morello' cherry is the quintessential sour cherry for the UK, being self-fertile and exceptionally hardy. It thrives even on north-facing walls, making it suitable for less sunny spots. Its bright red, tart fruits are perfect for pies and preserves. Another option is 'Nanking Cherry' (Prunus tomentosa), a smaller, bush-like tree native to Asia, which produces small, tart, red cherries and is also self-fertile, adding variety to your orchard.
Rootstock and Tree Size
The rootstock a cherry tree is grafted onto significantly determines its ultimate size and vigour. For smaller gardens or container growing, look for trees grafted onto dwarfing rootstocks like 'Gisela 5' or 'Colt', which typically result in trees that reach a manageable height of 2-3 metres. Semi-dwarfing rootstocks, such as 'Mazzard F12/1', will produce larger trees, often reaching 4-5 metres, requiring more space but potentially yielding more fruit. Standard trees, on vigorous rootstocks, can grow much larger, up to 6-8 metres, and are best suited for larger orchards or traditional garden settings.
Planting Your Cherry Fruit Tree
What's the best way to plant a cherry fruit tree for optimal growth and fruiting?
The ideal time to plant bare-root cherry fruit trees in the UK is during the dormant season, from late autumn through to early spring, typically between November and March. Container-grown trees, however, offer more flexibility and can be planted at any time of year, provided the ground is not frozen or waterlogged. When choosing a planting location, select a spot that offers full sun, as this is crucial for good fruit development and flavour. Cherries prefer well-drained, fertile soil. Avoid areas prone to waterlogging, as stagnant water can lead to root rot, a common problem for cherry trees.
Site Preparation
Before planting, prepare the soil thoroughly. Dig a hole that is at least twice the width and depth of the tree's root ball or spread roots. Incorporate well-rotted compost or manure into the excavated soil to enrich it and improve drainage. If your soil is heavy clay, adding grit or sand can help improve aeration and drainage.
When planting, ensure the graft union (the swollen knot where the scion meets the rootstock) remains at least 5-10cm above the soil surface to prevent the scion from rooting and compromising the rootstock's influence on vigour and size.
Planting Process
Gently loosen the roots of the tree if they are pot-bound. Place the tree in the centre of the hole, ensuring it is at the correct depth. Backfill the hole with the enriched soil, firming it gently around the roots to eliminate air pockets. Water the tree thoroughly immediately after planting to settle the soil and help establish the roots. For the first year or two, it's advisable to stake the tree to provide support, especially in windy locations, using a flexible tie to prevent damage to the trunk.
Spacing Considerations
The spacing required depends heavily on the rootstock and the variety's mature size. Standard trees might need 6-8 metres between them, while dwarf varieties on dwarfing rootstocks can be planted as little as 2-3 metres apart, or even in a hedgerow (espalier/cordon). Adequate spacing ensures good air circulation, which helps prevent fungal diseases, and allows each tree sufficient light and access to nutrients. Always consult the nursery's recommendations for specific spacing guidance.
Caring for Your Cherry Fruit Tree
How do you maintain the health and productivity of cherry fruit trees in the UK?
Consistent care is key to a thriving cherry fruit tree, ensuring it produces healthy blossom and a generous crop of fruit year after year. This involves careful attention to watering, feeding, pruning, and disease management, all adapted to the UK's specific climate.
Watering and Feeding
Newly planted trees require regular watering, especially during dry spells, to establish their root system. Once established, most cherry trees are fairly drought-tolerant, but they will benefit from deep watering during prolonged dry periods, particularly when fruits are developing. Overwatering should be avoided. For feeding, apply a balanced fertiliser in spring, such as a granular fruit tree fertiliser. A top-dressing of well-rotted compost or manure around the base of the tree in early spring is also beneficial, supplying nutrients and improving soil structure. Avoid excessive nitrogen, which can promote leafy growth at the expense of fruit production.
Pruning Cherry Trees
Pruning cherry fruit trees is often best carried out in summer, typically from late June to August, after the fruiting season. This 'summer pruning' helps to control the tree's size, improve light penetration, and reduce the risk of disease. Remove any dead, diseased, or crossing branches. Shorten new, vigorous shoots by about half, back to 5-6 leaves, which encourages lateral bud development for the following year's fruiting spurs. Avoid heavy winter pruning, as this can make cherry trees more susceptible to silver leaf disease and bacterial canker.
Pruning is vital for maintaining the tree's health and fruit yield. For young trees, focus on establishing a strong framework of branches. Older trees benefit from thinning out crowded fruiting wood to allow air and light to reach the centre of the canopy. It’s important to make clean cuts close to the main branch or trunk, using sharp secateurs or a pruning saw, and to sterilise your tools between cuts if disease is suspected, particularly when dealing with potential bacterial canker.
Pest and Disease Management
Cherry fruit trees in the UK can be susceptible to several pests and diseases. Birds are a common nuisance, often feasting on ripening fruit. Netting the trees as the fruit begins to change colour is the most effective method of protection. The most significant diseases are bacterial canker and silver leaf. Bacterial canker causes 'shotholes' in leaves and cankers on branches. Silver leaf, a fungal disease, can lead to leaf discolouration and eventual branch death. The best defence is good cultural practice: ensuring good air circulation, avoiding winter pruning, and promptly removing and destroying any infected material.
Fungal diseases are often exacerbated by damp conditions; ensuring good airflow through thoughtful pruning is your first line of defence.
For pests like aphids, a strong jet of water or insecticidal soap can be effective. Encouraging natural predators, such as ladybirds, also helps keep aphid populations in check. Always monitor your tree regularly for any signs of distress, pests, or disease, and act promptly.
Harvesting and Using Your Cherries
When and how should you harvest cherries from your UK fruit trees?
The exact timing for harvesting cherries varies depending on the variety and your local microclimate, but generally, sweet cherries ripen from late June through to August, while sour cherries are ready a little later, often in August. Look for fruits that are fully coloured and feel firm to the touch. They should detach easily from the stem with a gentle tug. Avoid picking cherries that are still hard or green; they won't ripen further once picked.
The Art of Picking
When harvesting, try to pick the cherries with their stems intact. This helps them store better and reduces the risk of bruising or juice loss. Use a ladder if necessary, but ensure it's stable. For larger trees, consider using a fruit picker tool that has a basket and a long handle.
For maximum flavour, harvest cherries in the late morning after the dew has dried, but before the heat of the day sets in.
Storage and Preservation
Fresh cherries are best eaten soon after picking. They can be stored in the refrigerator for a few days, ideally in a single layer in a container to prevent bruising, with a damp paper towel to maintain humidity. However, their quality deteriorates relatively quickly.
Cherries are wonderfully versatile and can be used in numerous ways:
- Eating Fresh: The most straightforward enjoyment, particularly for sweet varieties.
- Baking: Pies, tarts, crumbles, and cakes are classic uses for both sweet and sour cherries.
- Preserves: Jams, jellies, and compotes are excellent for preserving the flavour of cherries.
- Sauces: A cherry sauce pairs beautifully with duck, pork, or game meats.
- Drinks: Juices, cordials, and liqueurs can all be made from cherries.
Winter Fruit Trees for UK Gardens
While the primary focus is fruit production, remember that many cherry trees, particularly ornamental varieties, offer significant aesthetic appeal throughout the year. Even fruit-bearing trees provide the spectacular spring blossom, often a delicate pink or white, which is a hallmark of the season. The bare branches of some varieties can also offer interesting structure in winter. For those looking to extend their garden's yield and beauty, considering a range of fruit trees, such as pear tree, plum tree, or apple tree varieties, alongside your cherry fruit trees, can create a more diverse and productive garden ecosystem.
Common Questions About Cherry Fruit Trees
Here are answers to frequently asked questions about growing cherry fruit trees in the UK.
How long does it take for a cherry tree to produce fruit?
Most grafted cherry fruit trees, especially those on dwarfing or semi-dwarfing rootstocks, will begin to produce fruit within 2-4 years after planting. Standard trees on more vigorous rootstocks might take slightly longer, perhaps 4-6 years, before you see a significant harvest. The first few years are focused on the tree establishing a strong root system and a healthy canopy structure.
Can I grow a cherry tree in a pot?
Yes, you absolutely can grow cherry fruit trees in pots, provided you choose a dwarfing rootstock and a suitable container. Trees grafted onto rootstocks like 'Gisela 5' are well-suited for container cultivation. Ensure the pot is at least 40-50cm in diameter and depth, with good drainage holes. Use a good quality potting compost and remember that pot-grown trees will require more frequent watering and feeding than those planted in the ground.
What is the best cherry fruit tree for a small garden in the UK?
For a small UK garden, a self-fertile cherry variety grafted onto a dwarfing rootstock is ideal. Varieties like 'Lapins', 'Sunburst', or 'Stella' are good choices, as they don't require a pollination partner and will remain a manageable size. They can also be trained against a wall or fence as an espalier or fan, further saving space.
