When to prune taccarum weddellianum 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 taccarum weddellianum
Cut spent flower stalks and yellowing leaves cleanly at the base. Do not cut back healthy green foliage prematurely, as the leaves fuel the tuber for the following season.
Taccarum weddellianum is a rarely cultivated tuberous tropical aroid grown mainly for its dramatic foliage and unusual flowers. Like most aroids with seasonal dormancy, it needs only minimal pruning: remove spent flower spikes and cut back yellowing or frost-damaged leaves. No structural pruning is required.

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.
