When to prune cryptocoryne spiralis 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 cryptocoryne spiralis
Use sharp, clean scissors to cut individual dying or brown leaves off at the base of the petiole. Do not cut healthy green leaves.
Cryptocoryne spiralis is an aquatic plant that needs minimal pruning. Remove yellowing, brown, or dying leaves at the base as they appear — this is the extent of routine care. Healthy leaves should be left intact. The plant may melt and regrow after transplanting; trim melted leaves and let it recover.

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.
