When to prune alocasia black velvet 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 black velvet
Grip the petiole close to the base and cut cleanly with sharp, sterile scissors or shears. Allow the cut end to callous briefly before watering overhead.
Alocasia Black Velvet needs very little pruning. Each leaf grows individually from the corm — cutting a stem will not produce offshoots from that point. Remove leaves that have yellowed, browned, or died back by cutting the petiole cleanly near the base. Wear gloves: all Alocasia contain calcium oxalate crystals that irritate skin.

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.
