Germination
3-5 daysSeeds sprout within 3-5 days; tiny seedlings emerge with cotyledons
Keep soil moist but not soggy; maintain temperature between 50-70°F; ensure good drainage to prevent rot
Seedling
5-7 daysFirst true leaves appear; seedlings develop 1-2 true leaves and small taproots begin forming
Thin seedlings to proper spacing when they have 2-3 leaves; remove weaker plants to reduce competition; keep soil consistently moist
Vegetative Growth
10-15 daysRapid leaf and root development; above-ground foliage expands with 4-6 leaves; underground root expands into characteristic radish shape
Maintain consistent moisture; avoid excessive nitrogen fertilizer which promotes foliage over root development; thin if needed; monitor for pests
Root Development & Coloring
5-8 daysRoots swell to mature size with characteristic red shoulders and white base; distinctive bicolor pattern becomes visible at soil surface
Do not overwater at this stage as excess moisture can cause root splitting; ensure consistent moisture for smooth texture; light feeding if needed
Harvest Ready
Ready at day 25-30Roots reach 1-1.5 inches diameter; bicolor pattern is fully developed and vibrant; plants are at peak crispness and flavor
Check roots for size by gently brushing soil away; harvest promptly when ready to prevent woodiness; pull entire plant or cut greens separately

Harvest Tips
Harvest when roots reach 1-1.5 inches in diameter (typically 25-30 days). Gently brush away soil to check size without pulling. Harvest in the morning for crispest texture. Pull entire plant by grasping at base of stems and twisting, or cut with a knife just below soil line. Radishes are best enjoyed fresh immediately after harvest. Store unwashed roots in refrigerator in plastic bag for up to 2 weeks. Remove greens before storing if they look wilted.
