When to prune medlar in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune medlar
In the first three years, establish a clear trunk of 60–90 cm with four to five well-spaced scaffold branches. On established trees, remove only dead or diseased wood and any strongly crossing limbs. Work with the tree's natural tendency to spread — do not attempt to force a tight form.
Medlar is a low-maintenance fruiting tree that needs only light formative pruning when young and modest tidying once established. It naturally forms an attractive, gnarled shape. Remove dead, crossing, or diseased branches annually. Avoid heavy pruning — Medlar resents hard cutting and regenerates slowly. A light touch preserves the ornamental character and cropping.

Pruning medlar in the UK — FAQ
When should I prune medlar in the UK?
Prune medlar in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
Is it illegal to prune medlar in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check medlar for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

Annually for young trees; every two to three years on well-established specimens.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
