All About Growing Carrots ______________

Types to Try
Nantes are fast and easy to grow, and adapt to a range of climates and soils.
Chantenay carrots develop stocky roots that become sweeter as the soil cools in the fall.
Miniature carrots have small, shallow roots that are often quite sweet. They’re good for heavy clay soil.
Imperator carrots are long and need deep, sandy soil to thrive.
Danvers carrots make great juice, and the sturdy roots store well, too.
For more details, see our chart with descriptions of each type, cultural tips and varieties.
When to Plant
In the spring, sow carrot seeds in fertile, well-worked soil about two weeks before your last frost date. In cool climates, continue planting every three weeks until midsummer.
In summer, begin sowing seeds for fall and winter carrots 10 to 12 weeks before your average first fall frost. (To find your frost dates, click here and search for “frost dates.”) Many gardeners plant carrots after their spring peas are finished.
How to Plant
Prepare the planting bed by loosening the soil to at least 12 inches deep. Thoroughly mix in a 1-inch layer of mature compost or a half-inch layer of vermicompost (carrots love what earthworms leave behind).
Sow your seeds about a quarter inch deep and 2 inches apart, in rows spaced at least 10 inches apart; carrots do well in double or triple rows. Thin seedlings to 4 to 6 inches apart, depending on the variety’s mature size.
