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.
How to prune alocasia cuprea (red secret)
Hold the petiole near its base and cut cleanly with sterilised scissors or a knife. Never tug — this can disturb the corm. Wear gloves as the sap contains calcium oxalate crystals that irritate skin.
Alocasia cuprea (Red Secret) does not need pruning in the traditional sense. It grows from a central corm and produces individual leaves on petioles — there are no stems to cut back. Simply remove yellow, brown, or dead leaves by cutting the petiole as close to the base as possible. That is the full extent of pruning needed.

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.
