Orange carrots are the traditional standard, but you can try planting white, yellow, crimson, or even purple carrots, too. More important than color, though, is choosing the right root size and shape to suit your soil. Carrot size and shape varies by type, and there are five major categories. Ball-type, Chantenay, and Danvers carrots have blocky shapes that can handle heavy or shallow soil, while slender Nantes and Imperator carrots need deep, loose soil. All types are available in early and late cultivars; many are disease-and crack-resistant. Some catalogs don’t describe how to plant carrots by type, but will point out which cultivars do better in heavy or poor soil.
How To Plant
To produce the best crop possible, double-dig your planting area or build up a raised bed. Loose, rock-free soil is the goal. If you have heavy soil, add plenty of mature compost.
Start sowing this cool-weather crop 3 weeks before the last expected frost; plant again every 2 to 3 weeks after that. Most cultivars take 70 to 80 days to mature, so sow your last planting 2 to 3 months before the first expected fall frost. In Zone 8 and warmer, plant carrots in fall or winter.
