When to prune fragrant bouquet hosta 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 fragrant bouquet hosta
Snip spent flower scapes at the base once all flowers have finished. Cut foliage back to ground level in late autumn using clean shears, and dispose of debris to discourage overwintering pests.
Hostas need minimal pruning. Fragrant Bouquet is grown partly for its fragrant flowers, so enjoy the scapes and deadhead them once blooms finish. Cut all foliage to ground level in autumn after frost. Remove tattered or slug-damaged leaves during the season. No hard structural pruning is ever required.

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.
