When to prune paul's glory 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 paul's glory hosta
Snip spent flower scapes at soil level with clean shears. In autumn, cut all leaves to the ground and remove debris from the crown to limit slugs and fungal issues overwintering.
Paul's Glory Hosta requires only routine hosta maintenance. Remove flower scapes after the pale lavender blooms fade to keep the plant tidy. Cut all foliage to the ground in late autumn once frost has blackened it. During the season, remove any leaves showing disease or slug damage cleanly at the petiole base.

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.
