Troubleshooting
Nantes Carrot problems — and how to fix them
Nantes Carrot (Daucus carota subsp. sativus 'Nantes 2') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Carrot root fly
Larvae tunnel rusty galleries through the roots. Sow thinly to minimise thinning, use insect mesh or tall barriers, and time sowings to dodge fly peaks.
Splitting roots
The thin-skinned, low-core Nantes type is prone to splitting after irregular watering. Mulch and keep soil moisture even.
Forking
Stones and fresh manure fork the roots. Prepare deep, stone-free, unmanured soil for straight carrots.
Slow, patchy germination
Seed needs constant moisture to emerge. Keep the drill damp and prevent the surface crusting until seedlings appear.
