When to prune alocasia regal shields 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 shields
Use clean, sharp scissors to cut the petiole close to the base of the plant. Avoid tearing. Wipe tools with isopropyl alcohol before use.
Alocasia Regal Shields needs only cosmetic leaf removal — no shaping or structural pruning is required. Remove leaves when they yellow, brown fully, or become damaged, cutting the petiole cleanly at the base. In lower light or cooler winter conditions, older leaves may drop more frequently; this is normal and not a sign of a pruning problem.

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.
