When to prune hydrangea aspera 'villosa' 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 hydrangea aspera 'villosa'
Cut spent flowerheads back to the first pair of plump, healthy buds below the dead flower. Remove any completely dead or damaged stems at the base. If the shrub is becoming too large, selectively remove the oldest stems at ground level rather than shearing the whole plant.
Hydrangea aspera 'Villosa' blooms on old wood and needs only light pruning. Prune in early spring: remove dead stems and spent flowerheads down to the highest healthy buds. Avoid cutting back hard as you would a mophead — this removes this season's flower buds. The shrub is naturally large and architectural; work with that habit.

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.
