Notes Keep plants well weeded to reduce competition for nutrients are water. Mulch over the tops of mature carrots to keep their shoulders from turning green. Harvesting Can be harvested over a long period, but the longer plants are left in the ground, the more likely they are to be injured by insects or animals. Troubleshooting Viruses, nematodes, and soil-borne diseases can cause roots to become gnarled or misshapen. Try fast-maturing varieties to sidestep these problems.
