When to prune nantes carrot 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 nantes carrot
Cut bolt stems cleanly at or just below soil level. For damaged foliage, snip individual leaves at the base of the petiole with scissors to avoid disturbing shallow roots.
Nantes carrots need no routine pruning. Their main intervention is bolt removal: if a central flower stem emerges — common in heat or after a cold snap — cut it off at the base immediately to preserve root quality. Remove any damaged leaves as they appear. Tops stay on until harvest.

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.
