When to prune turnip 'purple top white globe' in the UK
Why the timing differs here

Thin to 4–6 inches apart by snipping at soil level. Cut bolt stalks flush at the base the moment they elongate. Harvest outer greens sparingly, leaving enough leaf area to continue feeding the root.
Turnip 'Purple Top White Globe' needs no pruning in a traditional sense. Thin seedlings early to allow roots to bulb up properly.

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.
