When to prune ctenanthe compressa 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 ctenanthe compressa
Use clean, sharp scissors to cut individual stems at soil level. Avoid snapping or tearing stems, which can introduce rot. There is no technique to encourage branching or denser growth through cutting on this species.
Ctenanthe compressa (Bamburanta) needs only tidying, not shaping. It is a clump-forming foliage plant that does not branch when cut. Remove dead, yellowed, or damaged leaves by cutting their stems at the base. No structural pruning is needed — the plant maintains its natural upright form on its own.

Is it illegal to prune ctenanthe compressa in spring or summer in the UK?

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.
