When to prune alocasia amazonica 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 amazonica
Use clean scissors or shears sterilized with isopropyl alcohol. Cut the petiole as close to the corm or base stem as possible. Avoid tearing, which can introduce disease. Wear gloves — all Alocasia parts are toxic and sap irritates skin.
Alocasia x amazonica rarely needs pruning beyond removing dead or dying leaves. It grows from a central corm and does not produce side branches to shape. Remove yellow, brown, or damaged leaves by cutting the petiole close to the corm base. This keeps the plant tidy and prevents rot.

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.
