Prof. Charles Hartman, Ph.D.Growing carrots starts with soil that crumbles like used coffee grounds. Heavy clay can bend the roots into crazy shapes.

Planting Windows
- Zones 3-5: Sow 2 weeks after last frost (May-June)
- Zones 6-8: Early spring or 10 weeks before first frost
- Zones 9-10: Fall planting avoids summer heat stress
Storage Solutions
- Refrigeration: 32-40°F in ventilated bags (3-4 weeks)
- Root cellars: Layer in damp sand (6+ months)
- Freezing: Blanch sliced carrots 3 minutes before packing
