Troubleshooting
Danvers Carrot problems — and how to fix them
Danvers Carrot (Daucus carota 'Danvers') 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 fly
Root maggots leave rusty, tunnelled damage. Use fine-mesh crop covers from sowing to harvest; avoid disturbing foliage in the evening. Danvers' stocky root tolerates minor surface damage better than thin types.
Green shoulders
Shoulders turn green and bitter when exposed to light. Mound soil over emerging crown tops as roots develop to keep them covered throughout growth.
Alternaria leaf blight
Dark lesions with yellow halos on foliage in warm, wet conditions. Rotate crops on a 3-year cycle, avoid overhead watering, and remove infected material promptly.
