When to prune nepenthes northiana 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 northiana
Snip dead leaves and pitchers at their base with sterile scissors. For stem trimming, cut just above a node — new growth will emerge from the cut point. Cuttings can be rooted in damp sphagnum.
Nepenthes northiana needs minimal pruning. Simply remove dead or yellowing leaves and old, dried pitchers as they appear to maintain good airflow and hygiene. If the vine grows too long for its space, trim back to a healthy node. This lowland species grows vigorously, so occasional stem management may be needed more often than most Nepenthes.

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.
