When to prune zebra plant (calathea zebrina) 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 zebra plant (calathea zebrina)
Remove individual yellow or dead leaves by cutting the petiole cleanly at the base. Trim brown tips with sharp, sterilised scissors at an angle that matches the leaf's natural taper.
Zebra Plant Calathea requires only cosmetic pruning — removing yellowed leaves and trimmed brown tips. This species is sensitive to stress; avoid cutting back healthy foliage. Focus on improving humidity and watering quality to prevent damage rather than pruning it away after the fact.

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.
