Growing Carrots: Easy Root Vegetables for Sandy Soil

Carrots are popular, easy-to-grow root vegetables that thrive in sandy soil, resist most pests/diseases, and tolerate frost as a late-season crop. Colors range from purple to white—not just orange.

Planting Carrots

• Sow outdoors 3–5 weeks before last spring frost.
• Soil must be stone-free, deeply tilled for straight roots.
• Don’t use fresh or recently rotted manure—causes forking and side roots (“legs”).
• Plant seeds 3–4 inches apart in rows ≥1 foot apart.

Care

• Gently mulch to retain moisture, speed germination, block sun from roots.
• Well-drained, loose soil prevents forking and stunting.
• At 1 inch tall, thin to 3 inches apart. Snip with scissors—pulling damages remaining roots.
• Water ≥1 inch/week.
• Weed diligently.
• Fertilize 5–6 weeks after sowing.
• Carrots sweeten after frosts. After first hard frost, cover rows with 18 inches shredded leaves for later harvest.

Harvest and Storage
