Planting tips

  • Use the paper towel seeding method for easy even spacing.
  • Soil should be very loose and fine; free from rocks and clods.
  • Carrots need full sun but cooler soil temperatures are helpful.
  • Try planting nearby plants that will shade the soil especially in a raised bed where soil temperatures get warmer. Consistent moisture is also helpful for producing tasty carrots.
  • Raised bed depth of 10-12 inches desirable for most carrots.
  • Fertilizer: Use organic fertilizers such as bone meal as radishes require a lot of P (phosphorus)
  • Number of plants per square foot: 16
  • Growing structures: None
  • Frost protection: None

Harvest

  • Harvest 60-80 days after sowing
    • Harvest when “shoulders” emerge and are approximately 3/4 to 1” in diameter (may vary by variety). 
    • Grasp carrot at the base of the foliage and gently pull straight up.
    • If carrots do not pull free easily, loosen surrounding soil with a garden fork.

Pests 

  • None of significance
