When to prune natal sundew 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 natal sundew
Peel or snip dead leaves cleanly at the base. Cut spent flower scapes at soil level once fully finished. Avoid touching or damaging the sticky active leaves.
Drosera natalensis requires no pruning in the traditional sense. Simply remove dead or spent leaves and old flower stalks as they appear. Active, glistening trapping leaves should never be cut — they are essential for the plant's nutrition. Keep intervention strictly to dead-material hygiene.

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.
