When to prune alocasia cuprea red secret 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.

Alocasia cuprea 'Red Secret' requires no routine pruning. Its jewel-like metallic leaves emerge one at a time from the central rhizome. Simply remove yellowing or damaged leaves by cutting the petiole cleanly at the base when they die back. Cutting healthy leaves reduces the plant's limited leaf count.

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.
