When to prune nepenthes sanguinea 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 sanguinea
Snip dead pitchers or leaves cleanly at the base with sterilised scissors. To shorten a vine, cut just above a node; the remaining stem will produce new side-shoots with pitchers over the following months.
Nepenthes sanguinea rarely needs pruning in the traditional sense. Remove individual pitchers or leaves only once they have fully browned and died back naturally. If the vine grows too long for your space, cut stems back to a node — the plant will resprout. Otherwise, leave it alone; unnecessary cutting disrupts pitcher production.

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.
