When to Plant Carrots

Carrot seedlings

Carrots are commonly grown in spring, fall, and winter in warm-winter regions. Carrots can be grown through the summer in mild to cool summer regions and surplus can be stored for winter.

Carrots may be seeded as early in spring as the ground can be worked. Make successive sowings of carrots at intervals of about 3 weeks in order to have a continuous supply of tender carrots throughout the season.

Carrots will grow on almost any type of soil as long as it is moist, humus-rich, loose, and free from clods and stones. Sandy loams and peats are the best.

Cover carrot seed about ½ inch on moist soils; less, usually about ¼ inch, on heavy soils.

With care in seeding, carrots will require little thinning. Carrots can stand some crowding, especially in loose soils. However, carrots should grow no thicker than 10 to 15 plants per foot of row.

Standard carrots are Chantenay, Nantes, and Imperator.

Carrots should be harvested and stored before the first hard frost occurs; the roots may be injured by cold.
