When to prune calathea picturata 'argentea' 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 picturata 'argentea'
Snip the entire petiole of any unsightly leaf at soil level using sterilised scissors. If tip browning is minor, trim only the dead portion following the leaf's natural edge.
Calathea Picturata 'Argentea' is a compact foliage plant requiring minimal pruning. There are no stems to cut back or shape. Remove dead, yellowed, or badly damaged leaves at their petiole base as they appear. The plant naturally sheds older outer leaves as it produces new growth.

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.
