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
No pruning at any stage. Thin crowded seedlings by snipping (not pulling) surplus seedlings at soil level to avoid disturbing neighbors. Leave all remaining foliage intact throughout the growing season.
Nantes 2 carrot is an annual root crop that needs no pruning. All foliage must remain to fuel root development. Removing tops during growth reduces yields. Thin seedlings to 5–7 cm apart after germination — this is the key management step. Harvest roots at 15–20 cm length before they become woody.

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.
