When to prune chimanta 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 chimanta sun pitcher
Snip dead pitchers flush at the base with clean scissors. Remove spent flower stalks at soil level after flowers fade.
Heliamphora chimantensis needs only light tidying. Remove dead, fully blackened pitchers at the base as they die naturally — mature pitchers can remain functional for many months. Do not cut healthy pitchers. Trim spent flower stalks after blooming. Like all Heliamphora, it is slow-growing and does not need regular pruning.

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.
