Given their ubiquity on the supermarket produce shelf and in restaurant salads, we suspect that many people take radishes for granted. Even gardeners are guilty: many plant quick-germinating radishes among other slower-growing vegetables such as carrots and/or cucumbers—prone to being overtaken by weeds—to mark their location so newly-emerged seedlings won’t be pulled out mistakenly as weeds!
Easy
Full sun.
Keep soil uniformly moist but soaked. As always, be sure to water gently when seeds are first planted and just after seedlings appear. Early morning watering is best.
Well-drained, loose, cool soil works best. Well-drained, loose, cool (45°F) soil works best.
50-65°F is ideal for growing plants.
Direct sow seeds outdoors in early spring after the danger of frost has passed. Plant again in early fall, per seed packet planting instructions. Depending on variety, radish plants typically mature 21-30 days from seeding.
Plant seeds ¼-½ ” deep. Thin 2″ seedlings to 2-3 inches apart (refer to seed packet for details).
3-10 days, 45-85° F. Seeds won’t germinate above 95°.
Organic fertilizer can be added at planting time.
Important to reduce weeds and conserve soil moisture.
Homegrown radishes grown from seed aren’t particularly prone to problems. Insect threats include flea beetles, aphids and caterpillars that will munch on the foliage. Cutworms can be a problem for seedlings.
For best results, rotate crops every 2-3 years.
Beans, beets, carrots, cucumbers, lettuce, melons, nasturtium, onions, spinach, squash and tomatoes.
Yes, especially since they’re so fast growing!
Pull up your radishes from the ground as soon as the roots start to stick up out of the soil. Don’t leave them for too long; otherwise they will become too tough and fibrous. Their flavor is dependent on temperature: generally the cooler it is, the milder they will be. Harvest them before it gets too hot.
