When to prune moon and stars watermelon 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 moon and stars watermelon
Pinch or cut the main vine tip a few nodes past the last set fruit. Trim fruitless laterals back to 2 leaves. Retain shading foliage near each melon.
Moon and Stars watermelon is a long-vining heirloom that benefits from tip pruning after 2 fruits per vine have set. Cutting the vine tip beyond the last fruit focuses plant energy into sizing those melons. Remove excess laterals in tight spaces, but leave adequate leaf cover to protect fruit from sunscald.

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.
