When to prune cryptocoryne crispatula var. balansae 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 crispatula var. balansae
Clip dying leaves at the base of the petiole with sharp aquatic scissors, working carefully to avoid uprooting the roots from the substrate.
Cryptocoryne crispatula var. balansae is a tall aquatic plant that needs little pruning. Remove old, brown, or dying leaves at the base to keep the plant healthy and maintain water quality. If older outer leaves become tatty while the center stays healthy, trim only the outermost leaves. No cutting back is needed.

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.
