When to prune calathea princeps 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 princeps
Cut individual leaf stems at the base of the plant using clean scissors. Do not cut healthy green leaves to 'shape' the plant.
Calathea Princeps needs minimal pruning — only remove dead, brown, or damaged leaves by cutting stems at the base. It is a compact clumping plant that maintains its own shape. Over-pruning can weaken it. Focus energy on correct watering, humidity, and indirect light rather than cutting.

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.
