When to prune colocasia 'coffee cups' 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 'coffee cups'
Remove individual yellowed or damaged petioles at the base with clean secateurs. In autumn, cut the entire plant to just above soil level before mulching the corm for winter protection.
Colocasia 'Coffee Cups' benefits from regular removal of dead, yellowing, or damaged leaves throughout the growing season to maintain its bold tropical appearance. Cut back all foliage to the ground in autumn before frost (in temperate climates) or as old leaves die back. No structural pruning is needed.

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.
