When to prune dionaea muscipula 'red dragon' 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 dionaea muscipula 'red dragon'
Use clean scissors or fingers to snap off entirely blackened traps or stalks at the rhizome base. Remove flower stalks early (when stem is 2–3 cm tall) unless seed production is the goal.
Venus flytraps need minimal pruning. Remove blackened or dead traps and flower stalks at the base — flowering drains energy and is best cut before it opens unless you want seed. Never trim healthy green traps. The plant naturally drops old leaves; your job is simply removing dead growth to prevent rot.

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.
