When to prune catesby's pitcher plant in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune catesby's pitcher plant
Use clean pruning scissors to cut dead pitchers and dried phyllodia flush with the rhizome. Remove flower stalks at the base once petals have dropped.
Sarracenia x catesbaei, a natural hybrid, follows the same seasonal cleanup routine as other Sarracenias. Cut dead or fully browned pitchers back to the rhizome in late winter before the new season's pitchers unfurl. Trim spent flower stalks after bloom. Healthy pitchers should never be removed — they are functional traps.

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.
