When to prune prunus 'accolade' 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 prunus 'accolade'
Build an open balanced framework in early years by removing badly placed shoots. On established trees, cut dead or crossing branches back to a healthy lateral or collar. Sterilise tools between cuts.
Prunus 'Accolade' requires modest pruning to maintain its graceful, arching form. Prune after flowering to avoid cutting off buds. In the first 2–3 years, carry out formative pruning to establish a balanced branch structure. After that, remove only damaged, diseased, or poorly placed growth.

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.
