Organic Carrots - Growing and Seed Saving Info Printable version of this page
| Types of Carrots |
| Carrots are often classified by their root shape: |
- Nantes Blunt tips; straight, cylindrical roots 5 to 7 inches long; sweeter than most other types; good raw eating. Prefers loose soil.
- Chantenay Shorter than other types, stocky, taper to a rounded tip; rich, sweet flavor and good storage potential. Coarser texture than others.
- Imperator Long, tapered roots with stocky shoulders and strong tops; slightly fibrous texture. Stores well. Most common type found in groceries. Prefers deep, sandy soil.
- Danvers Shorter than Imperator varieties, thick-rooted cylindrical shape, widely used in processing, good for juicing. Stores well. Performs well in heavy, clayey soil.
| Soil Requirements |
| Do best in fertile sandy loam, but will perform well under most conditions if appropriate varieties are chosen. For compact soils choose tapered carrots that can wedge their way into soils like Chantenays or Danvers types. Optimal soil temperature for germination is 55-75°F. |
| Bed Preparation |
| Best quality arises from raised beds, free of stones and debris. Imperator types should only be grown on raised beds that have 10-12 tilled zones. |
| Position |
| Full sun |
| Nutrient Requirements |
| Fertilize with the ratio of 1-2-2 (N-P-K) at the time of seeding and again when tops are 4-8". Potassium promotes solid, sweet carrots. |
| Seeding Depth |
| 1/4-1/2 |
| Seeding Rate |
| For early small bunching: ~45 seeds/ft; For full size ~30 seeds/ft; For soup size or storage ~15 seeds/ft |
| Plant Spacing |
| Thin to 1-2" depending on desired size |
| Row Spacing |
| 18-24" |
| When to Sow |
| Direct seed as soon as soil can be worked in the spring through mid-summer |
| Other Info |
| Weeding shortly after germination allows slow-growing carrots to get a head start against fast-growing weeds. |
| Frost Tolerant |
| Yes |
| Drought Tolerant |
| No |
| Heat Tolerant |
| Prolonged hot weather in later stages of development may stunt growth, and can cause strong flavor and coarseness in the roots. |
| Seed Specs |
| 11,000-37,500 seeds/oz (24,250 avg), 175-600M seeds/lb (288M avg) M=1,000 |
| Seeding Rate |
- Early bunching carrot plant approximately 45 seeds/ft,
- Full sized carrots plant approximately 30 seeds/ft, and for
- Storage varieties plant 15 seeds/ft.
- Early small bunching 45M seeds/1000(~ 1.9 oz), 1.4MM seeds/acre,(~ 5 lb), using ~45 seeds/ft, 18 row spacing;
- Full size 30M seeds/1000,(~ 1.3 oz), 1MM seeds/acre,(~ 3.3 lb), using ~30 seeds/ft, 18 row spacing;
- Storage 15M seeds/1000, (0.65 oz), 500M seeds/acre,(~ 1.7 lb), using ~15 seeds/ft, 18 row spacing. M=1,000, MM=1,000,000.
| Seed Coating / Pelleting Info |
| Some of the hybrid carrot varieties we carry receive an organic film coating applied to the seed, which make the seed easier to see during planting. |
| Harvest |
| Harvest when carrots have appropriate coloring and flavor has developed. Carrots hold well in the field for up to 3 weeks in the summer and longer in cool conditions. Some varieties, like Napoli, may be over wintered outdoors or in the high tunnel for an early spring harvest. For storage carrots dig roots after frost but before ground freezes. |
| Storage |
| Store topped carrots in near freezing temperatures with high humidity. Unwashed carrots store just as well as washed but may stain during storage. |
| Pest Info |
| Carrot Weevil and carrot rust fly are common pests. Floating row cover can be an effective control for the Carrot Weevil and Carrot Rust Fly. Other tips include delay sowing seeds until June to avoid the first wave of flies, as well as sowing carrots seeds thinly, as the carrot rust flies are attracted to the smell of bruised carrot foliage. |
| Disease Info |
| Fungal leaf blights caused by either Alternaria dauci or Cercospora carotae can cause severe defoliation and greatly reduce yields. White mold (Sclerotinia sclerotiorum) manifests as a cottony white mycelium around roots and lower plant parts, usually late in the season. See Cornell Universitys Vegetable MD Online for more information. |
| Other Known Issues |
- Misshapen Roots In general, carrots do not grow well in heavy soils. Long-rooted varieties such as the Imperator types may end up twisted, stunted or forked in such soils when they hit clumps or rocks. If you have heavy soil, add humus to loosen up the soil or grow shorter varieties, such as Danvers types.
- Greenish Shoulders When exposed to sunlight, the tops of carrots will often turn green. To prevent this from happening, hill up dirt around the tops of the carrots.
