Growth Stages
Germination & Seedling
7-10 daysSeeds sprout in 3-7 days with true leaves emerging. Tiny seedlings visible above soil with cotyledons first, then true leaves.
Thin seedlings to proper spacing once true leaves appear. Keep soil moist but not soggy. Provide good light to prevent leggy growth.
Vegetative Growth
10-15 daysFoliage expands with 4-6 leaves. Root begins swelling underground, though not yet visible at soil surface.
Maintain consistent moisture and thin ruthlessly to avoid crowding. Weed regularly. Apply light mulch to retain moisture.
Root Development
5-10 daysRoot bulb visibly enlarges and may push slightly above soil. Foliage becomes fuller and denser.
Continue even watering. Avoid overhead watering to prevent fungal issues. Check maturity by gently uncovering the top of the root.
Maturity & Harvest
1-3 days (harvest window is short)Root reaches desired size (typically 0.75-1.5 inches diameter for spring radishes, 1-3 inches for winter types). Skin color fully developed.
Harvest immediately when radishes reach ideal size; older radishes become woody, pithy, and bitter. Water until harvest.

Harvest Tips
Harvest spring and summer radishes when they reach 0.75-1.5 inches in diameter (typically 23-30 days). Gently pull from soil or dig to avoid breaking. Winter radishes are ready at 50-70 days and can be 2-3 inches in diameter. Harvest before the first frost or store in cool conditions.
