Gardener's Tips

Keep soil moist while seeds are germinating. Wet soil before planting. Mix seeds with dry coffee grounds for better seed distribution.   Sow seeds directly outdoors in early spring or late summer for a fall harvest.

Apply mulch once established. Prefers cool, moist soil. Plant every 3 weeks for successive harvest.

Cosmic Purple carrots grow best in loose, well-drained soil and full sun.

Should be directly seeded directly into the soil. Carrots do not want their roots disrupted and want to be able to send them down as soon as they are planted. 

As an open-pollinated variety, these seeds can be saved and replanted with proper isolation techniques—perfect for gardeners seeking seed sovereignty.

Harvesting Tips

• Begin checking size around the 2-month mark from planting date.

• Check for Size, Not Just Color: The tops may show some purple above the soil, but the best indicator of maturity is diameter—aim for ½ to 1 inch across at the top of the root.

• Loosen Soil First: Gently loosen the soil with a garden fork before pulling to avoid breaking these vibrant roots.

• For an even sweeter flavor, wait until after a light frost—cooler temperatures convert starches into sugars.

• Remove tops immediately after harvesting to prevent moisture loss.

• Store roots in a cool, humid environment, like a fridge or root cellar.
