When to prune alocasia scalprum 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 alocasia scalprum
Cut the entire petiole at base level with clean, sharp scissors. Sterilise blades between plants to prevent pathogen transfer.
Alocasia Scalprum needs no pruning beyond removing spent leaves. This rare compact species from Borneo grows sequentially and cannot be shaped. Prune only to remove yellowing, damaged, or dead foliage by cutting the petiole cleanly at the base to maintain plant health.

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.
