When to prune sun pitcher 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 sun pitcher
Snip fully dead pitchers at their base near the rhizome with clean scissors. Do not pull them, as the rhizome can be disturbed. Leave all green or partly green pitchers in place regardless of age.
Sun Pitcher (Heliamphora nutans) is a slow-growing highland carnivore that needs very little pruning. Remove pitchers only once they have fully died and browned. Because this species grows extremely slowly, take care not to remove any pitcher still showing live tissue. Flower stalks can be cut after seed set if desired.

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.
