When to prune nanking cherry in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune nanking cherry
Cut dead, damaged, or diseased branches back to healthy wood, making cuts 6 mm above a live bud or lateral branch. Reduce long branches by no more than one-third. Thin crossing shoots to open the centre. Prune on dry days with low humidity to reduce disease risk.
Nanking Cherry benefits from modest annual pruning to stay productive and manageable. Early summer is ideal for Prunus species as it reduces sap bleed and lowers disease entry risk. Remove dead, damaged, or crossing wood and shorten long branches by no more than one-third. Avoid fall pruning, which risks frost damage to new regrowth.

Pruning nanking cherry in the UK — FAQ
When should I prune nanking cherry in the UK?
Prune nanking cherry in early to mid spring.

Is it illegal to prune nanking cherry 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 nanking cherry for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
