When to prune nepenthes truncata 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 nepenthes truncata
Use clean scissors or a blade to cut dead pitchers and leaves flush to the stem. If a vine has become unwieldy, cut it back to a healthy node — the cut stem may eventually produce a side shoot.
Nepenthes truncata needs minimal pruning. Remove pitchers that have fully dried and browned, and trim any dead or yellowing leaves at their base. The plant grows slowly and vining stems rarely need cutting unless space is limited. Pruning does not stimulate branching the way it does in shrubs.

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.
