When to prune mountain sweet 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 mountain sweet pitcher plant
Snip dead pitchers and flat winter leaves at the base with clean scissors. Remove finished flower stalks at soil level to redirect energy to new pitcher growth.
Sarracenia rubra ssp. jonesii needs only seasonal cleanup. In late winter, cut away all dead or brown pitchers and winter phyllodia right down to the base before spring growth starts. Remove spent flower stalks after blooming. Never cut healthy green pitchers — they capture insects and fuel the plant.

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.
