How to Prune Apple Trees

Pruning an apple tree feels intimidating, but it rests on a handful of simple ideas: remove what's dead or in the way, let light into the middle, and cut lightly rather than hard. Get those right and you'll have a healthier tree and better fruit. This guide is part of our full apple growing guide.

Why and when to prune

Pruning does three jobs. It keeps the tree healthy by removing dead and diseased wood, it lets light and air into the canopy so fruit ripens and disease struggles to take hold, and it keeps the tree a sensible shape and size you can actually pick from. A tree left entirely unpruned doesn't die — but it becomes a congested tangle that fruits in tight, shaded clusters of small apples.

Timing depends on the type of tree. Free-standing apple trees — bushes, half-standards and standards — are pruned in winter, while dormant, any time from leaf fall in November through to bud break in early March. Winter pruning encourages vigorous growth, which is what an open-grown tree wants.

Trained forms — cordons, espaliers, fans and stepovers — are pruned mainly in summer, usually from mid-July into August. Summer pruning slows growth and encourages the tree to form fruiting spurs rather than more leafy shoots, which is exactly what you want from a tightly trained tree.

A quick note on tools: you want clean, sharp secateurs for thin wood, loppers for anything up to about thumb-thickness, and a pruning saw for larger limbs. Wipe blades with disinfectant between trees, especially if you're cutting out anything diseased.

The first cuts (dead, diseased, crossing)

Whatever the tree, start with the cuts that are never wrong. Gardeners remember these as the "three Ds" plus crossing wood.

1. Dead wood. Brittle, grey, lifeless branches with no green under the bark. Cut them back to healthy wood or to their point of origin.
2. Diseased wood. Anything showing canker (sunken, cracked bark) or the blackened tips of fireblight. Cut well back into clean wood and bin or burn the prunings — don't compost them.
3. Damaged wood. Snapped, split or rubbing branches, often from wind or a heavy crop.
4. Crossing branches. Where two limbs rub, they wound each other and let disease in. Remove the weaker or more awkwardly placed of the pair.

Do this first and you'll often find half the job is done, and the tree's shape suddenly makes more sense. Step back regularly and look at the whole tree rather than getting lost in one branch.

Creating an open goblet shape

Most free-standing apple trees are grown as an open-centred "goblet" or "wine glass" shape: a short trunk, then four or five main branches radiating outwards and upwards, with an open middle. The aim is a framework that lets light reach every branch and air move freely through the canopy.

Working on a bush tree in winter, after the first cuts above:

• Open up the centre. Remove branches growing into the middle, plus strong vertical shoots crowding it, so sunlight reaches the heart of the tree.
• Thin the congestion. Where branches sit too close, remove the weaker one. Aim for evenly spaced main branches you could pass a hand between.
• Shorten the leaders lightly. The leaders are the tips of your main branches. Trim roughly a third off the previous summer's growth, cutting to an outward-facing bud — this thickens the branch and encourages fruiting side shoots.
• Tidy the side shoots. Shorten over-long sideshoots, but don't strip them all off — many carry your spurs and fruit buds.

Once a tree has its framework, annual pruning is mostly maintenance: the three Ds, a little thinning, and keeping the centre open.

Spurs and tip-bearers (knowing your tree)

Before you prune hard, find out how your variety fruits, because it changes what you cut. Apples fall into two broad habits.

Spur-bearers carry fruit on short, stubby shoots called spurs that form along the older wood and live for years. Most popular UK varieties are spur-bearers — Cox's Orange Pippin, Egremont Russet, James Grieve, Sunset. These respond well to the leader-shortening method above, which encourages more spurs. Over many years spur systems get congested and can be thinned ("spur pruning") to improve fruit size.

Tip-bearers carry much of their fruit at or near the tips of the previous year's shoots, with fewer spurs. Worcester Pearmain, Bramley's Seedling (partially) and Discovery lean this way. The trap here is obvious once you know it: if you routinely shorten every shoot tip, you cut off next year's fruit. With tip-bearers, prune more lightly — remove whole crowded or worn-out shoots rather than trimming every tip, and leave plenty of one-year-old shoots unpruned to fruit.

Summer pruning cordons and espaliers

Trained trees — cordons, espaliers, fans and stepovers — earn their keep in small gardens and against walls, and they're almost always grown on dwarfing rootstocks so they stay compact and fruitful. If you're planning a trained tree, our guide to choosing apple rootstocks explains which to pick — M9 and M26 are the usual choices for these forms, as a vigorous rootstock would overwhelm the framework.

These forms are kept productive by summer pruning, typically from mid-July to late August once the lower part of the new shoots has gone woody and stiff. The principle is simple: you're converting leafy growth into fruiting spurs and keeping the tree tight to its wires.

The classic method (often called the Modified Lorette system) goes like this:

1. Find this summer's new side shoots growing from the main stems or existing spurs.
2. Shorten shoots growing directly from a main stem to about three leaves above the basal cluster of leaves (roughly 7–8cm).
3. Shorten shoots growing from existing spurs to about one leaf above the basal cluster.
4. Leave the leaders until they reach the length you want, then prune them too.

Summer cutting starves the shoot of the leaves it would use to make vegetative growth, so instead it forms fruit buds for next year. Do a little tidying again in autumn if secondary regrowth appears. Done each year, this keeps a cordon or espalier cropping heavily in a fraction of the space a bush tree needs — which is why they're a great fit alongside other fruit trees in pots and small-garden growing.

Common mistakes

A few errors come up again and again, and all are easy to avoid.

• Pruning too hard. The single most common mistake. Removing huge amounts in one go triggers masses of upright water shoots and little fruit. Prune a bit each year rather than a brutal one-off.
• Pruning at the wrong time. Winter for free-standing apples, summer for trained forms — and never winter for plums or cherries. Mixing these up causes disease or lost crops.
• Shearing a tip-bearer. Trimming every shoot tip on a tip-bearing variety cuts off next year's apples. Know your tree first.
• Leaving stubs or cutting flush. Both prevent clean healing. Cut to a bud, or back to the branch collar.
• Topping the tree. Beheading a too-tall tree just provokes a thicket of regrowth at the cut. Lower height gradually over a few years instead, taking whole limbs back to a lower branch.
• Doing nothing for years, then everything at once. A light annual prune beats an occasional savage one every time.

Renovating a neglected tree over several years

Inherited an overgrown old apple tree? It can usually be brought back into shape and good cropping — but the work must be spread over three or four winters, never crammed into one. A drastic single-winter overhaul causes the water-shoot explosion every time.

Work to a plan across the seasons:

• Year one. Do all the safe cuts first: dead, diseased, damaged and crossing wood. This alone transforms a neglected tree and lets you see its structure. Remove one or two of the very worst large, crowded or low branches — but no more.
• Year two. Open up the centre by removing more inward and overcrowding branches, and take out a couple more major limbs if needed. Start thinning congested spur systems.
• Year three onwards. Continue thinning and shaping, gradually lowering height by cutting tall limbs back to a suitable lower side branch. Shorten and thin until you've an open, manageable framework.

Throughout, keep removing no more than about a quarter of the canopy a year, and rub off the water shoots that appear each summer where you've made big cuts. Feed and mulch the tree well while it recovers, and don't expect a heavy crop for a season or two — you're trading short-term fruit for a healthy tree for decades to come.

A renovated tree responds slowly but surely, and once it's back to a tidy goblet the upkeep is just that light annual winter prune.
