When to prune calathea bachemiana 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 bachemiana
Cut the petiole cleanly at its base using sterilised scissors. Remove entire leaves rather than leaving stubs, which can harbour fungal issues in humid conditions.
Calathea Bachemiana is a clump-forming houseplant that does not require shaping or structural pruning. Remove dead or yellowed leaves at the base of their petioles as they occur. The narrow silvery-green leaves are produced continuously from the rhizome, so cosmetic tidying is all that is needed.

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.
