When to prune monstera deliciosa borsigiana 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 deliciosa borsigiana
Use clean, sharp pruning shears to cut stems just above a node. Wipe cuts with a clean cloth. Aerial roots can be tucked into the pot or trimmed short — do not strip them all off.
Monstera deliciosa var. borsigiana grows vigorously and benefits from annual pruning to manage its size. Remove dead or yellowing leaves at the petiole base. Trim aerial roots only if they are in the way — do not remove them entirely as they support uptake. Cut back overly long stems to a node to control spread.

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.
