Growing Pear Trees in a British Garden

Why Pears Are Worth the Effort

Pears have a reputation for being awkward, and there is some truth in it. They flower early, they dislike cold winds, and they can sulk for years before cropping. Yet a well-sited pear tree is one of the most generous things you can plant in a British garden. Once established, it will crop reliably for decades, often outliving the person who planted it. Varieties such as 'Conference' and 'Doyenné du Comice' remain deservedly popular, but there is a wider range available than most garden centres suggest, including old cooking pears that turn soft and fragrant in a late autumn oven.

The trick is to work with the tree rather than against it. Give pears the warmth, shelter and drainage they crave, choose a rootstock that suits your space, and you will be picking fruit within three or four years.

Site, Soil and Shelter

Pears originate from warmer regions than apples, and they never quite forget it. A south or west-facing wall, fence or boundary is ideal, because the stored heat radiates back at night and helps both flowering and fruit ripening. In colder parts of the country, a wall-trained tree is not a luxury but almost a necessity.

Shelter matters as much as sun. Cold east winds during blossom time will deter pollinators and can strip young fruitlets. Avoid frost pockets at the bottom of a slope, where cold air collects on still spring nights.

Soil should be deep, fertile and free-draining. Pears hate waterlogged roots and will develop a stunted, yellow-leaved look if they sit wet through winter. If your soil is heavy clay, plant on a slight mound or a raised bed, and work in plenty of well-rotted organic matter. A slightly acid to neutral pH of around 6.0 to 7.0 suits them well. Before planting, dig a hole wider than it is deep and fork the base to break up any pan.

Choosing a Rootstock

Rootstock is the quiet decision that determines everything about the mature size of your tree. Pick the wrong one and you will spend the next twenty years on a ladder you did not want to own.

• Quince C — the most dwarfing option, producing a tree of roughly 2.5 to 3.5 metres. Best on good soil; needs staking for life and suits containers or small plots.
• Quince A — semi-dwarfing, reaching around 3.5 to 4.5 metres. The sensible all-rounder for most gardens and the most widely sold.
• Pyrodwarf — slightly more vigorous than Quince A but with better anchorage and tolerance of heavier soils.
• Pyrus communis (seedling pear) — a full standard of 6 metres or more, only for larger gardens, orchards or field margins.

Note that some varieties, notably 'Conference' and 'Williams' Bon Chrétien', are incompatible with Quince C and need Quince A or a double-worked tree. Ask before you buy.

Pollination and Varieties

Most pears are not self-fertile, so plant two varieties that flower at the same time. The flowering groups run roughly from early to late, and as a rule a tree will pollinate another within one group of its own. 'Conference' is partially self-fertile and will crop alone in a warm garden, but even it does better with a partner.

Good pairings for a small garden include 'Conference' with 'Concorde', or 'Beth' with 'Williams' Bon Chrétien'. If space is tight, a family tree with two or three varieties grafted onto one trunk solves the problem neatly.

• Dessert pears: 'Comice' for rich, buttery flesh; 'Beth' for early picking; 'Concorde' for heavy, reliable crops.
• Culinary pears: 'Catillac' and 'Black Worcester' hold their shape and colour beautifully when baked or poached.
• Perry pears: 'Hendre Huffcap' and 'Thorn' are grown for cider-style perry, with tannin and acidity that eating pears lack.

Planting, Training and Feeding

Bare-root trees go in between November and March, whenever the ground is not frozen. Container-grown trees can be planted almost any time, but autumn remains best. Set the tree so the graft union sits around 10 centimetres above soil level.

Pears can be grown as bushes, half-standards, espaliers, fans or cordons. A fan against a sunny wall is a classic and productive choice, though it demands summer pruning to keep the framework tidy. Bush trees need only light formative pruning in winter, removing congested growth and shortening leaders by about a quarter until the frame is built.

Feed in late winter with a balanced general fertiliser, and mulch with garden compost or well-rotted manure, keeping it clear of the trunk. Water young trees generously in their first two summers; after that, established pears are reasonably drought-tolerant.

Harvest, Storage and a Word on Cider

Pears are unusual in ripening from the inside out, so a fruit that feels hard on the tree may already be ready. Pick when the stalk parts easily with a gentle upward twist, and when the skin colour begins to lighten. Early varieties like 'Beth' are best eaten within a fortnight; later ones store well in a cool, dark, frost-free shed, laid in single layers on slatted trays.

If you have a glut, cider making is a natural destination. True cider is made from apples, but perry — its pear equivalent — is a West Country tradition worth reviving. Perry pears are high in tannin and unpalatable raw, but pressed and fermented they give a light, dry, faintly floral drink. The fruit should be fully ripe and slightly softened; leave it to rest for a week or two after picking before milling and pressing. Ferment cool and slowly, and be patient. Like the tree itself, perry rewards those willing to wait.
