When to prune schismatoglottis motleyana 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 motleyana
Cut individual petioles to the base with clean scissors. To manage size, unpot in spring and separate rhizome offsets by hand, repotting each division into fresh soil.
Schismatoglottis motleyana is a clumping tropical aroid that requires only light grooming. Remove old or damaged leaves by cutting the petiole at the base. Trim faded spathes. Division rather than pruning is the main way to manage size — split congested clumps in spring rather than cutting back hard.

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.
