When to prune alocasia calidora 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 calidora
Cut the entire petiole (leaf stalk) as close to the base or main stem as possible using clean, sharp scissors or pruning shears. Do not pull or tear the stalk, as this can damage the corm.
Alocasia Calidora needs minimal pruning. It does not branch, so there is nothing to shape. Simply remove yellowing, damaged, or dead leaves by cutting the petiole cleanly at the base with sterilized scissors. This keeps the plant tidy and directs energy to healthy foliage. Beyond that, leave it alone.

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.
