When to prune calathea wiotii 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 calathea wiotii
Snip dead or damaged petioles at soil level with clean scissors. Sterilise tools between cuts if the plant has shown any signs of fungal or bacterial leaf spots.
Calathea Wiotii needs no structural pruning. It is a compact, rhizomatous houseplant grown purely for its decorative foliage. Pruning is limited to removing dead, yellowed, or damaged leaves at the base of the petiole. The plant naturally cycles through leaves as it matures, so some leaf loss is normal.

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.
