When to prune roseraie de l'hay rose 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 roseraie de l'hay rose
Cut out any dead, diseased or oldest unproductive canes to the base. Reduce the remaining framework by up to one-quarter overall. Deadhead through summer to maintain the repeat-flowering cycle.
Roseraie de l'Hay is a repeat-flowering Rugosa shrub of considerable vigour, eventually forming a large, dense mound. It needs only light annual pruning — remove dead and very old stems in late winter and reduce height modestly. Heavy pruning is counterproductive with Rugosas; the plant does best when pruning is restrained.

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.
