When to prune turnip 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 turnip
Cut individual outer leaves near the base for greens. If a flower stalk appears, cut it off at the base immediately — this may briefly extend root quality but bolting typically signals the end of the harvest window. No other pruning is needed.
Turnip is a root vegetable that does not require pruning. Leaves (turnip greens) can be harvested by removing outer leaves without impacting root development. Remove bolting flower stalks promptly if you want to extend root quality, though once a turnip bolts the root becomes woody and is usually best harvested or discarded.

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.
