Black radishes and other winter radish varieties are hardy, long-storing, and packed with bold, peppery flavor. They’re perfect for late-season planting and add a unique touch to winter meals.
Best Time to Plant Winter Radishes
Sow seeds in late summer to early fall, about 8–10 weeks before your first expected frost. In mild climates, plant through fall for winter harvests.
Soil and Bed Preparation
Winter radishes need loose, fertile soil at least 8 inches deep for proper root development. Work in compost before planting to provide steady nutrients.
Sowing and Spacing
Plant seeds ½ inch deep, 3–4 inches apart. Thin seedlings promptly to ensure large, uniform roots.
Care Tips
- Keep soil evenly moist to prevent toughness.
- Use mulch to regulate soil temperature.
- Rotate planting areas each year to avoid pest buildup.
Harvesting and Storage
Harvest when roots reach 3–4 inches in diameter, before the ground freezes. Store in a cool, humid place or in the refrigerator for months.
My Experience
I’ve grown black radishes for decades, appreciating their bold flavor in winter salads and roasts. With good timing and loose soil, they grow reliably large and store beautifully.
