Apple

The most forgiving fruit tree for a UK garden: disease-resistant varieties exist for almost every situation, and a well-chosen rootstock keeps even a small garden in apples for decades.

Sowing Guide

What you'd find on the seed packet

Sow Depth

Bare-root: roots spread out in a hole wide enough to take them without bending, planted to the same depth as the nursery soil mark on the trunk

Spacing

Depends entirely on rootstock: roughly 1.5–2m for dwarfing (M27/M9), 3m for semi-dwarf (M26), 4–5m or more for vigorous rootstocks (MM106 and above)

Germination

Not grown from seed for fruiting (seedlings don't come true to variety). Always bought as a grafted tree on a named rootstock

Thinning

Not applicable at planting; fruitlets are thinned in June once the tree is established and cropping

Grower's Note

Rootstock choice matters more than variety for how big the tree ends up. Check whether the chosen variety is self-fertile or needs a pollination partner flowering at the same time before buying just one tree.

Recommended Varieties

'Sunset' holds an RHS Award of Garden Merit, is genuinely self-fertile so one tree is enough, and gives a Cox-like flavour with far better disease resistance than Cox itself. 'Egremont Russet' also holds an AGM and has a distinct nutty russet flavour, but is only partially self-fertile and crops better with a second tree nearby. For organic growing, The Organic Gardening Catalogue lists 'Adam's Pearmain', an 1826 Norfolk heritage variety with strong resistance to scab, mildew and canker, well suited to disease-prone organic orchards.

Plant Spacing

See rootstock spacing above

Best Grown In

Open ground or a large container on dwarfing rootstock

Conditions

Full sun, sheltered from strong wind, free-draining soil. Avoid a known frost pocket, since apple blossom can be damaged by late spring frosts

Grower's Note

Bare-root planting (November to March, while dormant) is cheaper and generally establishes better than a potted tree planted in summer.

Watch Out For

Codling moth larvae tunnel into the fruit itself. Pheromone traps from May and removing any fallen, maggoty fruit promptly both help

Apple scab shows as dark, scabby patches on leaves and fruit, worse in wet springs. Rake up and bin fallen leaves in autumn rather than composting them

Canker (sunken, cracked bark, often on a wound or pruning cut) can girdle and kill a branch. Cut back to clean wood well below the visible damage

Common Questions

About growing Apple in the UK

Do I need two apple trees to get fruit?

Often, yes. Most apple varieties need a different variety flowering at the same time nearby for pollination, though some self-fertile varieties exist. Check the variety's pollination group before buying just one tree, or choose a confirmed self-fertile one if space only allows for one.

What rootstock should I choose for a small garden?

M27 or M9 for the smallest trees (1.5–2m, good for pots), M26 for a slightly larger tree that's still manageable (around 3m). Vigorous rootstocks like MM106 are really for orchard-scale space.

When do I prune an established apple tree?

Winter, while the tree is dormant and leafless, for most free-standing forms. Trained forms (espalier, cordon) are pruned in summer instead, to control vigorous new growth rather than shape the whole tree.

How long until an apple tree fruits?

On a dwarfing rootstock, often 2–3 years for the first proper crop. On a vigorous rootstock, it can take 4–6 years. Remove any fruit that sets in the first year so the tree puts its energy into establishing roots instead.
