When to prune colocasia tea cup 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 colocasia tea cup
Remove old petioles cleanly at the base with sharp, clean shears. In frost areas, cut all growth to 2–3 inches above the corm after foliage is killed by cold, then mulch heavily.
Colocasia 'Tea Cup', known for its upward-cupping leaves, needs very little pruning. Simply remove yellowed, damaged, or spent leaves at the petiole base to keep the plant healthy and attractive. The distinctive cupped leaf form is a natural trait — do not cut or trim leaves to alter their shape.

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.
