Without pruning, they can become straggly and less productive. Cutting back branches and shoots in the dormant season will concentrate sap flow in spring into fewer buds, resulting in strong growth. By contrast, summer pruning limits vigour by removing nitrogen-rich young growth, and will promote flower and fruit formation.
So, in the early years of a fruit tree’s life, when you want it to grow strongly to create a sturdy framework of branches, it’s vital to prune in the dormant season. Once it has reached the required size and shape, most of the pruning can be done in summer.
Before you start pruning, make sure you’re familiar with our list of plants to avoid pruning in winter – take a look at our guide to summer pruning fruit trees for more information.
Read our advice on pruning fruit trees in winter, below.
Remove thin or damaged shoots
First remove any thin or damaged shoots and branches. Cut them back to where they sprout from the branch or main stem. When the tree isn’t in leaf, it’s much easier to get the right results, as you can clearly see the form of the plant as well as the position of the fruit buds.
Prune last season’s growth
Next, prune last season’s growth back. You need to reduce the previous season’s sideshoots back to between four and six buds from the base. The younger stems are silvery-grey in colour, so are easy to distinguish from the old, brown branches.
Cut the main leader
Finally, cut the main leader at the top of the tree to around half its length, just above an outward facing bud, with a sloping cut to help shed water.
Pruning mature trees
Medium and large apple trees benefit from having vigorous young shoots cut back and overcrowded branches thinned in winter. Open up the centre of the tree so air can circulate and sun can reach developing fruits in summer.
You can also remove old branches that are unproductive or badly placed, cutting back to where they join a thicker branch or the trunk.
Where established apples and pears have been pruned this way in previous years, the mass of strong regrowth that is promoted can be removed altogether or thinned out.
Shaping up young trees
Prune freshly planted apple and pear trees, and those up to four years old, in winter so they form a good framework of branches.
Reduce the height of the leading shoot and cut back side branches to channel sap into a few buds low down. This strengthens the main shoots.
Continued winter pruning in the early years encourages small buds to form near the base of stems that will develop into fruiting spurs. Pruning young trees also reduces unwanted top growth and conserves energy, which can then be used to boost the root system.
