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 calathea sanderiana

Snip individual damaged or dying leaves off cleanly at the petiole base using sterilised scissors. Avoid tearing, which can stress the plant and open wounds to infection.

Calathea Sanderiana (Pin-stripe Calathea) requires very little pruning. The plant does not benefit from cutting back stems or shaping. Routine care involves removing yellowed, scorched, or dead leaves at the base to keep the clump healthy and prevent fungal issues.

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.
