When to prune ridge gourd 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 ridge gourd
Pinch the main vine tip above a node. Allow 2–3 laterals to grow and pinch their tips 2–3 nodes after a female flower. Remove crowded or unproductive shoots to improve light and airflow.
Ridge gourd (Luffa acutangula) responds well to pruning for higher yields. Pinch the main vine tip after 10–15 feet or once it has set a few fruits to promote lateral branching. Keep 2–3 strong laterals and remove weak or excess shoots. Prune laterals 2–3 nodes beyond a female flower to direct energy into fruit set.

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.
