When to prune schismatoglottis wallichii 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 schismatoglottis wallichii
Cut individual petioles at or just above soil level using clean scissors. Remove faded spathes at their stem. Keep tools sterilised to prevent rot spreading in the humid conditions this species prefers.
Schismatoglottis wallichii is a low-growing tropical aroid that needs minimal pruning. Remove yellowing or damaged leaves by cutting the petiole cleanly at the base. Spent spathes can be removed as they fade. No hard pruning is required; the plant maintains a tidy clumping form naturally.

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.
