When to prune quince 'smyrna' 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 quince 'smyrna'
Maintain an open-center form. Each year remove 20–25% of the oldest, least productive wood and any crossing or inward-facing branches. Shorten the previous season's longer shoots by up to one-third to stimulate fruiting laterals near the tips. Always use clean, sharp tools — quince wounds can harbor fireblight.
Quince 'Smyrna' (a Turkish heritage variety prized for fragrance and size) is a vigorous grower that needs consistent annual pruning to prevent overcrowding and maintain yield. Like all quince, it fruits on tips of shoots from the previous year's growth, so a balance of thinning old wood and retaining new is key.

Pruning itself is not illegal, but destroying an active nest is.

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.
