When to prune alocasia portora 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 portora
Sever the petiole at its base with sterilized scissors or a sharp blade. Wipe blades with isopropyl alcohol between cuts to avoid spreading any disease.
Alocasia Portora requires no shaping or structural pruning. Its large, upright leaves emerge sequentially from a central stem. Remove individual leaves only when they yellow, brown, or are physically damaged, cutting the petiole cleanly at the base. This is purely cosmetic maintenance, not pruning in any traditional sense.

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.
