When to prune heliamphora ionasi 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 heliamphora ionasi
Cut dead pitchers at the base with clean, sterilized scissors. Remove spent flower stalks once fully dried. Avoid cutting any green or partially functional tissue.
Heliamphora ionasi is one of the larger Heliamphora species and shares the same low-pruning needs as the genus. Remove fully dead pitchers at the base as they appear. Avoid cutting healthy pitchers or flower scapes prematurely. Spent flower scapes can be snipped once dry. No shaping or hard pruning is ever 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.
