Germination
7-10 daysSeeds sprout and cotyledons emerge from soil
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing early to prevent overcrowding. Maintain soil temperature around 60-70°F for optimal germination.
Seedling/Leaf Development
2-3 weeksTrue leaves develop and the plant establishes a small rosette of feathery foliage
Thin to 4 inches apart once second true leaf appears. Remove weeds carefully to avoid root disturbance. Keep soil consistently moist.
Root Development
3-4 weeksRoot begins elongating underground as foliage grows. Above-ground greens become more robust.
Maintain consistent watering to prevent splitting and cracking. Reduce nitrogen fertilization to avoid excessive leaf growth. Ensure loose soil to allow root expansion.
Bulking/Maturation
2-3 weeksRoot reaches full length (6-8 inches) and thickens. The white root becomes crisp and develops its mild flavor.
Continue consistent watering. Monitor for pests and diseases. Check root size by gently uncovering crown; harvest when roots reach desired size.
Harvest Ready
Ready to harvestRoots are firm, white, and reach 6-8 inches long with tender texture and mild, slightly sweet flavor
Harvest at peak crispness before roots become overly large (which increases woodiness). Can harvest at smaller sizes (4-5 inches) for more tender texture.

Harvest Tips
Harvest when roots reach 6-8 inches long and 1-1.5 inches in diameter. Gently uncover the crown to check size without pulling. Harvest in the morning for maximum crispness. Pull roots carefully to avoid breaking. In cool climates, can leave in ground and mulch for extended harvest. Roots are best harvested within 2-3 weeks of maturity; older roots become woody and hollow. Store harvested radishes in refrigerator with tops removed for up to 3-4 weeks.
