When to prune alocasia polly 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 polly
Cut the entire leaf stalk to soil level with clean scissors. Do not tear or pull the petiole, as this can damage the rhizome. Removing spent leaves promptly also reduces the risk of fungal issues in the humid conditions Alocasia prefers.
Alocasia Polly grows by pushing new leaves from its central rhizome — it does not branch, so pruning for shape is not applicable. Remove yellowing or spent outer leaves by cutting the petiole cleanly at soil level. This is normal maintenance as the plant cycles through leaves. Wear gloves, as the sap contains calcium oxalate crystals.

Pruning alocasia polly in the UK — FAQ
When should I prune alocasia polly in the UK?
Prune alocasia polly in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune alocasia polly in spring or summer in the UK?

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.
