- Plant 4-6 weeks before the average date of last frost, after aged manure or organic fertilizer has been worked into soil.
- Direct sow seeds ½ inch to an inch deep and one inch apart in rows 12 inches apart.
- Thin to about 2-inch spacings. Crowded plants will not grow well.
- Radishes need sun. If they are planted in too much shade—or even where neighboring vegetable plants shade them—they put all their energy into producing larger leaves.
- Practice three-year crop rotation.
- Plant consecutively every two weeks or so while weather is still cool for a continuous harvest of radishes.
- Plan on a fall planting. You can plant radishes later than any other root crop in late summer or early fall and still get a harvest.
- Radishes require well-drained soil with consistent moisture. Keep soil evenly moist but not waterlogged.
- Thin radishes to about an inch apart when the plants are a week old. You will be amazed at the results.
- Radishes will be ready to harvest quite rapidly, as three weeks after planting for some varieties.
- Do not leave in the ground long after mature stage, their condition will deteriorate quickly.
- Cut the tops off short, wash the radishes and dry them thoroughly. Store in plastic bags in the refrigerator.
Radish greens can be stored separately for up to three days.
- ‘French Breakfast’ late maturing variety, does well in moderate heat.
‘Burpee White’ spring variety, white skin.
