When should I sow carrot seeds?

Question:

When should I sow carrot seeds?

Answer:

Sow carrot seeds at a depth of 1/4 to ½ inch beginning in early April in central Iowa.  For a continuous harvest, make additional plantings every 3 to 4 weeks.  The last practical planting date for carrots is August 1. 

Space rows 18 to 24 inches apart.  If necessary, thin the seedlings within a few weeks of germination.  After thinning, seedlings should be spaced 2 to 3 inches apart.
