Planting & Care
  • Radishes germinate and grow best in cool temperatures of 55°F to 65°F. Warmer temperatures result in poor flavor and bolting.
  • Begin sowing 3 to 6 weeks before the last frost date. Plant seeds 1/4 to 1/2 inches deep.
  • Thin spring varieties to 1/2 to 1 inch apart. Thin larger winter radishes to 6 inches.
  • Space rows 12 inches apart
  • Radishes can also be sown in an open bed and thinned to ideal spacing
  • Radishes help break up the soil for slower maturing carrots, turnips and parsnips when they are sown together
  • For a continual harvest, sow in 1 to 2 week intervals until temperatures average 60°F. Resume planting again in fall when the temperatures cool. Or make a single spring planting of different varieties that will mature at different times during the season.
  • Radishes mature quickly and can be interplanted with later maturing vegetables such as cabbage, tomato or squash
Problems
Root maggots
