Rhaphanus sativus


There are few vegetables that grow as quickly and easily as radishes. (A great reason to plant them with children.) In less than a month from planting from seed, these crunchy, peppery radishes will be ready for serving in salads.

Some types are ready in as little as three weeks from seeding. Larger types, called daikon or winter radishes, require 50 to 55 days to mature. Because they germinate and grow so quickly, radishes are ideal to seed interspersed with slow-to-emerge crops such as carrots and parsnips. The radish seedlings break the soil crust for the slower-growing root crops, and by the time the carrots or parsnips need more space, the radishes will be ready to harvest.

Harvest Tips
Harvest radishes as soon as they are large enough to eat. The longer they remain in the ground, the spicier they become. Overmature radishes become woody, roots crack, and plants develop a seed stalk.
