When to prune yellow pitcher plant 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 yellow pitcher plant
Cut dead pitchers and spent flower stalks down to the rhizome using clean scissors. Do not cut into living green pitchers or the rhizome itself.
Yellow Pitcher Plant benefits from a tidy-up in late winter before new growth emerges. Remove the previous season's dead pitchers and flower stalks by cutting them at the rhizome level. Pitchers that are still partially green can be left until they brown completely. Beyond this seasonal cleanup, no pruning is needed.

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.
