When to prune alocasia sarawakensis 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 sarawakensis
Cut the petiole flush with the base using clean, sharp scissors or shears. Wipe blades with isopropyl alcohol between cuts to prevent pathogen spread, especially on a rare species.
Alocasia sarawakensis is a low-pruning plant. It does not branch and cannot be trimmed to a desired shape. Maintenance is limited to removing individual leaves as they age and die. Cut the complete petiole at the base with sterile scissors. Healthy foliage should be left entirely intact to fuel the rhizome.

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.
