Training a young apple tree into cordon form

Why a cordon suits the English garden

English orchard keeping has always been about making the most of small spaces. A cordon is a single-stemmed apple tree trained at a 45-degree angle against a stake or wire. It is the perfect choice for a rural cottage garden, a narrow allotment plot, or a sunny wall where a full standard tree would never fit. Plant a row of cordons just 60–90 cm apart and you create a productive fruiting hedge that is easy to pick from and simple to net against birds.

The cordon relies on summer pruning to keep it compact and to persuade the tree to form fruit spurs rather than long, unruly branches. It is a traditional skill, once common in English kitchen gardens, and it remains one of the most rewarding ways to grow apples in a limited space.

Choosing the right maiden tree

Start with a maiden – a one-year-old tree with a clean, straight stem and no side branches. Choose a spur-bearing variety on a dwarfing rootstock. M9 is ideal for most gardens, giving a tree that reaches about 1.8–2.4 m when trained. M27 is even smaller but needs richer soil and more careful watering. Avoid tip-bearers, which fruit at the ends of long shoots and resent the hard pruning a cordon requires.

• Egremont Russet – reliable, nutty flavour, excellent keeper.
• James Grieve – juicy, early, crops well as a cordon.
• Fiesta – heavy crops, good disease resistance.
• Sunset – small, sweet, perfect for a sunny wall.
• Ashmead's Kernel – old English variety, vigorous but trainable.

Buy bare-root between November and March. This gives the tree time to settle before spring growth begins.

Planting and the first winter prune

Drive a sturdy wooden stake, about 2.4 m long, into the ground at 45 degrees. The stake should be firm – a young cordon will carry a surprising weight of fruit in later years. Plant the maiden so the graft union sits 5–8 cm above soil level. Tie the stem to the stake with soft twine or rubber ties, using a figure-of-eight loop to prevent rubbing.

After planting, cut the leader back by one third to a downward-facing bud. Shorten any side shoots to three buds. This first cut seems severe, but it encourages the tree to push out strong new growth from the base of the stem. Water well and mulch with well-rotted manure, keeping the mulch clear of the trunk.

Summer pruning for compact spurs

The magic of cordon training happens in late July and August. At this time, cut every side shoot that is 20 cm or more back to three leaves above the basal cluster – the tight rosette of leaves where the shoot joins the main stem. Do not prune the main leader. Instead, tie its new growth gently to the stake as it extends.

This summer pruning redirects the tree's energy into forming fruit buds and keeps the cordon compact. If you prune too early, the tree may produce secondary growth; if you leave it too late, the shoots will be woody and less productive. Late July to mid-August is the sweet spot in most English gardens. Remove any shoots growing from the base of the tree or below the lowest intended spur.

Winter training and long-term care

In winter, while the tree is dormant, shorten the previous year's leader by about one third, cutting to a bud. Prune any remaining side stubs back to one bud. Each year the cordon extends by 30–45 cm, and the spur system thickens along the stem. After four or five years, the cordon will reach the top of its support and can be kept there by pruning the leader back to a permanent spur.

Water young trees in dry spells, feed with a balanced fertiliser in spring if growth is weak, and check ties regularly. A well-trained cordon will crop for 10–15 years. In rural areas, watch for bullfinches in late winter – they will strip fruit buds if the tree is not netted. With patience and a sharp pair of secateurs, your cordon will become one of the most productive corners of the garden.
