When to prune fork-leaved 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 fork-leaved sundew
Snip or pull away dead stems and leaves at their base. For congested clumps, remove older bare stems entirely. Cut spent flower scapes back to the basal leaves after flowering.
Fork-leaved Sundew is a vigorous sundew that needs very little pruning. Remove dead or dried leaves from the base as the plant grows upward. If a clump becomes very congested, thin it by removing older stems. Spent flower stalks can be cut after seed set. Otherwise, leave healthy dew-bearing leaves alone.

Pruning fork-leaved sundew in the UK — FAQ
When should I prune fork-leaved sundew in the UK?
Prune fork-leaved sundew in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

How often does fork-leaved sundew need pruning in a British garden?

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.
