When to prune alice's 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 alice's sundew
Gently peel away fully dried outer leaves from the rosette base — they usually detach cleanly. Snip spent flower scapes at the base with fine sterile scissors before seed pods split if you want to prevent seeding. Do not remove living sticky leaves.
Alice's Sundew needs almost no pruning. Remove dead or browned outer leaves by gently pulling them free from the rosette base as they die. Flower scapes can be trimmed once blooms fade to prevent self-seeding, or left if you want seedlings. Avoid touching or removing the dewy, glistening carnivorous leaves.

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.
