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 fontanesii

Cut stems to within a few centimetres of the soil with sharp, clean secateurs. Wear gloves as the sap is a skin irritant. Mulch over the corm in colder climates after cutting back.

Colocasia 'Fontanesii' benefits from removal of yellowing, damaged, or old leaves throughout the growing season. In frost-free gardens, cut back hard in late autumn or after frost blackens foliage. Indoors, remove spent leaves as they appear. No shaping is needed — the plant regrows vigorously from the corm.

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.
