When to prune colocasia crown of tonga 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 crown of tonga
Cut individual petioles at the base with clean shears. For container plants brought in for winter, cut all frost-killed growth back to the soil level once danger of frost has passed and store the corm dry.
Colocasia 'Crown of Tonga' (taro) benefits from occasional maintenance pruning. Remove older, yellowing outer leaves to keep the plant tidy and direct energy to new growth. In frost-free gardens or containers, cut back dead or tatty foliage in late winter. Do not over-prune; this is a vigorous grower and rarely needs heavy cutting.

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.
