Carrot Growing Guide Daucus carota subsp. sativus Crop Rotation Group Umbelliferae (Carrot and root family) ● Soil Well drained soil rich in organic matter, but with no manure added prior to planting. Use well aged compost or vermicompost to condition compacted soil. Position Sun or partial afternoon shade. Frost tolerant Tops tolerate light frost; roots survive hard freezes. Feeding Soil quality is more essential that supplemental feeding. Spacing Single Plants: 3" (10cm) each way (minimum) Rows: 3" (10cm) with 5" (15cm) row gap (minimum) Sow and Plant Sow direct into soil in spring. Make a second sowing for a fall crop in mid to late summer. Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area. 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.
