A well-pruned apple or pear tree is a pleasing sight: an open framework of branches, plenty of healthy fruiting wood and, with luck, a generous crop to look forward to.
Pruning helps keep fruit trees healthy and productive, but it can be difficult to know where to begin. How much should you remove? Which branches should stay? And what happens if you cut off too much?
The good news is that pruning doesn’t need to be complicated. Take your time, understand what you’re trying to achieve and let the shape of the tree guide you.
Why prune apple and pear trees?
The aim of winter pruning isn’t simply to make a tree smaller or tidier. It’s about creating a strong, open structure that allows light and air into the canopy while encouraging a good balance between new growth and fruit production.
Removing dead, damaged and badly positioned branches also helps maintain the tree’s health and prevents branches from rubbing against one another.
Perhaps most importantly, good pruning makes it easier for sunlight to reach developing fruit, helping it ripen.
When should you prune?
Established, free-standing apple and pear trees are generally pruned during their dormant period, after the leaves have fallen and before growth begins again in spring.
Choose a dry day and avoid pruning when conditions are very cold.
There is an important exception. Apples and pears trained as restricted forms – such as cordons and espaliers – are usually pruned in summer to control their growth and maintain their shape.
Young trees also need a slightly different approach while their permanent framework is being established.
Before making the first cut
Stand back and look at the whole tree.
It’s tempting to start cutting immediately, but a few minutes spent studying its shape can prevent you from removing branches you’ll later wish you’d kept.
Look for dead, diseased or damaged wood first. Then identify branches that cross or rub against one another, grow towards the centre of the tree or make the canopy particularly congested.
Try to imagine the finished tree before you begin.
For most established trees, you’re aiming for an open, balanced framework rather than a perfectly symmetrical shape.
Start with the three Ds
A useful place to begin is with the three Ds: dead, diseased and damaged wood.
Remove these branches first, cutting back to healthy wood or to an appropriate branch junction.
Next, look for branches that cross or rub. Where two branches compete for the same space, keep the stronger or better-positioned one and remove the other.
You can then turn your attention to congested areas and branches growing inwards towards the centre of the tree.
Work gradually, standing back every few cuts to see how the shape is developing.
How much should you remove?
This is where restraint matters.
Removing too much in a single winter can stimulate the tree to produce lots of vigorous upright shoots, often called watershoots. The result can be more leafy growth rather than the balanced fruiting tree you were hoping to create.
As a general guide, avoid removing more than around a quarter of the canopy in one year.
If an old tree has become badly overcrowded or neglected, don’t try to correct everything in one session. Renovating it gradually over two or three winters is usually kinder to the tree and produces a better result.
Sometimes the best pruning decision is simply to stop.
Know what you’re cutting
Before shortening branches, take a closer look at the buds.
Apple and pear trees produce both growth buds and fruiting buds. Fruiting buds tend to be plumper and rounder, while growth buds are generally smaller and lie closer to the stem.
Many varieties produce fruit on short, stubby shoots known as spurs, which can remain productive for several years. Others produce more of their fruit towards the ends of longer shoots.
Knowing whether your tree is mainly spur-bearing or tip-bearing can influence how you prune it. Shortening the wrong shoots too enthusiastically on a tip-bearing variety can mean removing much of the following season’s potential crop.
If you know the variety you’re growing, it’s worth checking its fruiting habit before you start.
Make clean cuts
Use clean, sharp secateurs for smaller stems and loppers or a pruning saw for larger branches.
When shortening a young shoot, make a clean cut just above a healthy outward-facing bud. This encourages new growth to develop away from the centre of the tree rather than back into it.
When removing a whole branch, cut carefully at its natural junction rather than leaving a long stub.
Large branches need particular care. Their weight can cause the bark to tear as they fall, so removing them in stages is safer for both you and the tree.
What about watershoots?
Strong, upright shoots can appear in the canopy, particularly after heavy pruning.
Remove those that are badly placed or crowding the centre of the tree, but don’t automatically cut away every upright shoot. Some can be useful for replacing older branches and developing new fruiting wood.
Again, it’s about balance rather than making the tree perfectly tidy.
Take extra care with older trees
An old apple or pear tree can have tremendous character as well as value for wildlife, so approach renovation with patience.
Begin with dead and unsafe wood, then gradually open congested areas over several years. Retaining veteran branches, cavities and deadwood can sometimes be valuable for wildlife where they don’t present a safety problem.
Very large, damaged or structurally unsafe trees are best assessed by a suitably qualified arborist rather than tackled from a ladder with a saw.
Prune with a purpose
Perhaps the most useful question to ask before every cut is: why am I removing this branch?
If you have a clear answer – it’s dead, it’s rubbing against another branch, it’s blocking light or it’s upsetting the tree’s structure – the cut probably has a purpose.
If you’re not sure, leave it and look again later.
Pruning apple and pear trees isn’t about cutting as much as possible. It’s about making a small number of thoughtful cuts that help create a healthy, balanced tree.
Take your time, keep stepping back and remember that you can always remove another branch – but you can’t put one back.
