|'Early Scarlet Globe' is generally ready for harvest 24 days after sowing. Oval roots with strong tops. Good for harvesting spring through fall. Bright red skin and white meat that rarely becomes pithy. Depending on the variety you want to grow, your radishes will have different sowing times. Small globe types should come first. Plant diakon types after the hottest days of summer or they will bolt.
Radishes like light, sandy soil which is cultivated deep, depending on the length of the variety you are growing. Sow short rows 6 inches apart, and water the seed bed if weather is dry to encourage rapid germination. Diakon types should be sown 8-10 inches apart. Globe types should be mature within a month, and should be eaten then before they become dry or pithy. If they bolt, you can use the seedpods in stirfry, and they are spicy like the root. Diakon and winter radishes can take as long as 3 months to reach harvesting size.
