Germination
3-7 daysSeeds sprout and first cotyledons emerge within 3-5 days in cool soil (50-70°F)
Keep soil consistently moist. Thin seedlings at this stage to prevent overcrowding. Remove debris to prevent damping off
Early Vegetative
7-10 daysTrue leaves develop, with 2-4 leaf pairs visible; small taproot begins to enlarge slightly
Thin to proper spacing (2 inches apart) by gently pulling crowded seedlings. Water consistently. Mulch to retain moisture and suppress weeds
Root Development
10-15 daysVisible globe or oblong swelling at soil surface; leaves grow to 3-4 inches tall; roots bulk rapidly
Maintain even soil moisture and consistent cool temperatures. Side-dress with compost if needed. Monitor for pest damage on foliage. Avoid high nitrogen
Maturity
2-3 days (very short window)Roots reach 1-1.5 inches diameter (globes) or 3-4 inches long (icicle shape); crisp, white, slightly spicy flesh; skin color develops fully
Begin harvesting immediately once mature—leaving in ground too long causes woodiness and cracking. Keep watering consistent until harvest
Harvest
1 day (harvest before overmaturity)Radishes at peak crispness and flavor; skin glossy and firm; leaves still green and fresh
Harvest in morning after dew dries for best crispness. Pull gently or use a spoon to loosen soil. Remove tops and store in refrigerator

Harvest Tips
Harvest when roots reach 1-1.5 inches in diameter for globes or 3-4 inches long for icicle types. Peak flavor occurs at this size; radishes become woody and bitter if left too long. Harvest in the morning when soil is cool and roots are crispest. Succession plant every 2 weeks for continuous harvests from spring through fall
