The key to good carrot production is soil preparation. Straight, uniform root development occurs when carrots are planted in deep, fertile, well drained, loamy soils with a pH of 5.5 to 7.0. Root quality is best when soil temperatures are 60 to 70 F. Add composted organic matter to dry soil; do not use fresh manure and avoid excess nitrogen fertilizers which can cause splits and rough hairy roots.
Direct seed carrots from early spring through summer by planting seeds thinly, about 3 to 4 seeds per inch and about 1/4 to 1/2 inch deep; allow 12 to 16 inches between rows. Cover the seeds with vermiculite or sifted compost to prevent crusting and help retain even moisture. Make additional plantings every three weeks through midsummer for continuous supply and fall harvest.
Keep plants well weeded to reduce competition for nutrients in the soil. When carrots are emerging, sprinkle the row often with a fine gentle mist of water to prevent soil crusting. Mulch to keep soil cool, conserve moisture and to keep exposed shoulders from turning green and bitter.
Harvesting and Storing Carrot
Carrots are best harvested any time their color is bright; this is when their flavor and texture are optimum. Remove ripe carrots carefully to avoid doing damage to other carrot roots nearby. Carrots will remain fresh in the soil for several months. For extended storage, wash carefully to avoid injury or store unwashed and topped at 32 to 34 degrees F with high humidity.
Carrot Insect and Disease Information
Carrot fly maggots can be controlled by covering the rows with an insect barrier fabric at planting. Practice a 3-year crop rotation to help avoid various carrot blights. Carrot weevil problems can be minimized by cleaning up garden debris in autumn.
Carrot Yield Information
Carrots are normally planted several times throughout the year and each harvesting should be the number given.
