Germination & Seedling
2-3 weeksSeeds sprout within 4-7 days. First true leaves emerge, appearing deeply lobed and slightly fuzzy.
Keep soil moist but not soggy. Provide cool conditions (60-70°F ideal). Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
2-3 weeksPlant develops feathery, pinnately lobed foliage. Root begins elongating underground; foliage is lush and green.
Maintain consistent moisture and cool temperatures. Mulch around plants to conserve moisture and keep soil cool. Remove any competing weeds.
Root Elongation
2-3 weeksThe distinctive long, slender white root extends deeper into the soil. Foliage continues to grow but slows relative to root development.
Ensure deep, loose, well-draining soil so roots can elongate without obstruction. Avoid compacted soil. Continue steady watering.
Root Maturation
1-2 weeksRoot reaches full length (12-18 inches) with a crisp, white, tender appearance. Foliage remains green and healthy.
Monitor for bolting (flowering) which signals maturity. Maintain cool conditions to prevent bitterness. Watch for pests near harvest time.
Harvest
Harvest window is 1-2 weeksRoot is fully mature, crisp, and ready to pull from the ground.
Harvest before hot weather or plants will bolt and roots become woody. Pull gently or loosen with a garden fork for long roots.

Harvest Tips
Harvest when roots reach 12-18 inches long and approximately 1-1.5 inches in diameter at the top. This typically occurs 50-70 days after sowing. Harvest before temperatures exceed 75°F as heat causes bolting and woody roots. Grasp the plant at the crown and pull steadily, or loosen soil with a garden fork first for easier extraction of long roots. Store harvested radishes in a cool cellar or refrigerator (32-40°F) in plastic bags for 2-3 weeks. Can also be stored in sand.
