The carrot (Daucus carota) is a cool season vegetable plant that originated in Afghanistan. Originally grown for medicinal purposes, it is now cultivated for its long, edible taproot. Carrots grow best in warm, moist soil and can be harvested within 60 to 70 days of planting. Plant your carrots seeds in mid-April.
Til the planting bed to a depth of 10 inches. Break up the soil until it is free of clods and has a powdery consistency.
Pour 1/2 cup of urea per 100 square feet of planting area and use a gardening fork to blend it into the soil to a depth of 10 inches. Rake the bed until it is smooth and level.
Plant the carrot seeds 1/4 inch deep, 1 inch apart. If you are planting more than one row of carrots, space the rows 12 to 18 inches apart. Water the planting area to a depth of 2 inches and keep the soil moist until the carrot seeds germinate, generally within two weeks of planting.
Supply the carrots with at least 1 inch of water per week. If you do not receive that much rain, irrigate the carrots with a soaker or standard hose.
Remove weeds in the planting area as soon as they emerge. Extension agents with the University of Illinois suggest using a hoe to shallowly dig out the weeds.
Sidedress 1/2 cup of urea per 100 square feet of carrot bed 30 days after planting by digging a trench, 3 inches away but alongside the carrot row. The trench should be 2 inches in depth. Spread the urea along the length of the trench and cover it with soil. Water the entire bed until the top 2 inches of soil is moist.
