When to prune stromanthe jacquinii 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 stromanthe jacquinii
Cut unwanted stems cleanly at soil level with clean, sharp scissors. Remove spent flower stems at their base once blooms have faded. Do not attempt to shape the clump by trimming leaf tips — this disfigures the foliage.
Stromanthe jacquinii is a clump-forming tropical that does not benefit from structural pruning. Simply remove dead, yellowed, or damaged leaves by cutting stems at the base. Spent flower stems should be removed after blooming. Beyond that, this species requires no cutting to maintain its natural form.

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.
