When to prune bottle gourd in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune bottle gourd
Pinch the main growing tip cleanly above a leaf node at 10–12 leaves. Allow 2–3 laterals to develop; pinch each lateral 2–3 leaves beyond the first female flower. Remove overcrowded shoots to improve airflow.
Bottle gourd benefits significantly from pruning to boost fruit yield. Pinch the main vine tip after 10–12 leaves to encourage lateral side shoots, which are the primary fruiting branches. Remove excessive lateral shoots beyond the first two or three, and pinch laterals again after 2–3 leaves beyond the first female flower to direct energy into fruits.

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.
