When to prune alocasia portodora in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune alocasia portodora
Cut yellowing or dead stems cleanly at their base with sterile snips. Twist or cut offsets away from the base if separating pups, leaving roots intact.
Alocasia 'Portodora' needs minimal pruning. Remove lower leaves as they naturally age, yellow, or become damaged by cutting the stem close to the main trunk. This is a statement foliage plant — do not cut back healthy leaves. Removing pups (offsets) from the base can keep growth tidy.

Is it illegal to prune alocasia portodora in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check alocasia portodora for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
