When to prune 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 pitcher plant 'ventrata'
Snip dead pitchers and leaves flush to the stem with sterile scissors. To control vine length, cut just above a node — use the cutting for propagation if desired. Avoid removing healthy green pitchers even if they look old.
Nepenthes × ventrata rarely needs pruning. Remove individual pitchers once they brown and die naturally, and trim dead or yellowing leaves at the base. If vines grow too long, cut just above a node — the cutting roots readily. Beyond tidying dead growth, this vigorous climber needs little intervention.

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.
