Apples and pears: summer pruning

Summer pruning is mainly for apples and pears trained as restricted forms: cordon, espalier, fan, pyramid, spindlebush. Trees grown as standards or bushes are managed with winter pruning.

Summer prune when the bottom third of the new shoots is stiff and woody. Generally, this will be from late-July for pears and mid- to late August for apples and about ten days later in the north. To reduce the possibility of secondary growth it can be delayed until Sptember, when larger terminal (end) buds

Buds are typically found on stems, where they can be apical (found at the tip) or axillary (found between leaf axils) and may develop into leaves, shoots or flowers. have formed at the shoot tips and the shoots have stopped growing.

Judge the exact timing according to the vigour of the plant, the weather and locality.

Summer pruning involves cutting back new shoots to allow light to reach the fruit.

New shoots are stiff and woody along their bottom third, with dark green leaves and a cluster of leaves at the base.

1. Cut back new shoots (laterals) more than 20cm (8in) long growing from the main stem to three leaves above the basal cluster of leaves. Do not prune new shoots that are less than 20cm (8in) long as they usually terminate in fruit buds

2. Cut back new shoots growing from existing sideshoots (sub-laterals) to one leaf above the basal cluster
3. Remove any upright, vigorous growth completely
4. If secondary growth occurs after summer pruning, prune back any re-growth in September (or October if pruning later) to one leaf beyond the previous cut.
5. If this is a persistent problem, leave some longer shoots unpruned as these will draw up the sap
   Sap is a fluid that circulates through a plant's vascular system, in a similar way to blood moving through our veins. Phloem sap carries the sugars produced in the leaves by photosynthesis down to roots and other storage organs, as well as carrying minerals and hormones. Xylem sap is watery and transports nutrients absorbed by the roots upwards to the rest of the plant. Some plants leak sap from wounds or pruning cuts, and this is known as bleeding. and grow at the expense of secondary growth elsewhere. Cut these back to one bud

Although pruning shouldn't cause any particular problems for the plant, you may see some other common issues:

Fruit: protecting from frost

Apple canker

Apple scab and pear scab

Fruit: biennial bearing
