When to prune alocasia plumbea 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 plumbea
Cut the entire petiole (leaf stem) cleanly at soil level using sterilized scissors or a sharp knife. Do not leave stubs, which can rot and invite disease.
Alocasia plumbea needs minimal pruning. Remove yellowing, dead, or damaged leaves at the base of the petiole as they appear. Never remove healthy green leaves — each leaf feeds the corm. Occasional tidying keeps the plant looking clean, but no structural pruning is required or beneficial.

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.
