When to prune monstera obliqua 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 monstera obliqua
Cut the petiole of dead or damaged leaves close to the main stem using fine, sterilised scissors. Take care not to disturb the fragile remaining leaves. Never remove healthy growth unless a runner has escaped its climbing support.
Monstera obliqua is extremely delicate with highly fenestrated, fragile leaves — handle and prune as little as possible. Only remove dead or damaged leaves by cutting cleanly at the petiole base. Do not cut healthy stems unnecessarily. Because it is a slow, rare species, pruning for shape or size is almost never warranted.

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.
