When to prune nepenthes rafflesiana 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 rafflesiana
Cut dead leaves and pitchers cleanly at their junction with the main stem. To control vine length, trim stems just above a node. Healthy tip cuttings (15–20 cm) can be rooted in sphagnum moss.
Nepenthes rafflesiana is a tropical pitcher plant that needs minimal pruning. Remove dead, yellowing, or withered leaves and spent pitchers by cutting cleanly at the stem. Leggy vines can be trimmed back to encourage bushier growth, and healthy stem tips removed can be rooted as cuttings. Avoid over-pruning the active growing points.

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.
