When to prune tropical pitcher plant 'ventrata' 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 tropical pitcher plant 'ventrata'
Cut stems just above a healthy node using clean, sharp scissors. Each pruned tip will typically produce one or two lateral shoots, each capable of forming new pitchers.
Nepenthes 'Ventrata' benefits from occasional pruning to control its vining growth and encourage branching. Trim long stems back by one-third to one-half to prompt side shoots. Remove dead or empty pitchers and yellowed leaves any time. Without pruning, stems become leggy and pitcher production declines on older nodes.

Without pruning, stems become leggy and pitcher production declines on older nodes.
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.
