When to prune rattlesnake plant 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 rattlesnake plant
Snip dead or yellowed petioles at soil level. For brown-edged leaves you want to keep, trim the margin with scissors, following the leaf's natural curve.
Rattlesnake Plant (Calathea lancifolia) is a low-maintenance houseplant that rarely needs pruning. There are no stems to shorten. Remove leaves that have turned entirely yellow or brown by cutting the petiole cleanly at the base. Occasional trim of brown leaf margins is the only other task.

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.
