When to prune calathea orbifolia 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 orbifolia
Cut the entire leaf stalk (petiole) at soil level using clean scissors. Do not tear or pull, as this can damage the rhizome. Never cut into healthy green leaves to try to shape the plant — it will not branch from a leaf wound.
Calathea orbifolia is a rhizomatous perennial that does not respond to pruning in the conventional sense. New leaves grow from the base, not from stems. Simply remove yellowing, old or damaged leaves by cutting the stalk at soil level. Beyond that, no pruning is needed or beneficial — the plant shapes itself.

Pruning calathea orbifolia in the UK — FAQ

Prune calathea orbifolia in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune calathea orbifolia in spring or summer in the UK?

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.
