Troubleshooting
Chantenay Carrot problems — and how to fix them
Chantenay Carrot (Daucus carota subsp. sativus 'Chantenay Red Cored') 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
Low-flying flies lay eggs whose larvae tunnel the roots. Sow thinly, avoid thinning that releases scent, and use fine mesh or 60 cm barriers.
Forked or split roots
Stones, fresh manure and irregular watering deform roots. Use stone-free soil, no fresh manure, and water evenly.
Green shoulders
Exposed root tops turn green and bitter in light. Earth up or mulch over the crowns as they swell.
Erratic germination
Carrot seed is slow and needs steady surface moisture. Keep the seed drill damp until seedlings emerge; don't let it crust over.
