When to prune alocasia regal shield 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 regal shield
Cut the petiole close to the base with clean, sterilised scissors or a blade. If the plant goes dormant in winter and all foliage collapses, cut stems to soil level and reduce watering until new growth emerges in spring.
Alocasia Regal Shield rarely needs pruning beyond removing dead or yellowing leaves. It grows upright from a central rhizome and does not branch, so there is nothing to shape or cut back. Simply remove spent leaves cleanly at the base of the petiole. Dormant plants may die back entirely — do not discard; wait for regrowth.

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.
