Summer Cross No. 3 is an F1 hybrid daikon radish bred for late summer and fall harvests, reaching maturity in about 55 days. This compact variety produces long, straight roots when given the deep, friable soil it craves, making it a reliable choice for gardeners who want to extend the radish season into cooler months. Plant it 2 inches apart in rows spaced 12 inches apart, and you'll have crisp, harvestable roots before the first hard frost arrives.

This F1 hybrid thrives in the shoulder seasons when other radishes bolt and turn bitter. Its frost tolerance means you can sow in midsummer and harvest deep into fall, giving you weeks of productive growing beyond what spring varieties offer. The compact growth habit means it won't sprawl across the garden, and the straightness of its long roots makes both harvesting and storage straightforward.
Summer Cross No. 3 is grown for its edible roots, which are harvested and used fresh in salads, slaws, and pickled preparations typical of late-season radish cooking. As a daikon-type radish, it suits both raw consumption and cooked applications where its crisp texture holds up well.

Direct sow seeds in midsummer for late-summer and fall harvest. Sow at a depth appropriate for small radish seeds (typically 1/4 to 1/2 inch) directly into the garden bed, spacing them 2 inches apart. Water gently to keep the seed bed consistently moist until germination occurs at temperatures between 45 and 75°F.
Harvest Summer Cross No. 3 radishes approximately 55 days after sowing, or when roots reach desired size. Long daikon radishes can be pulled when they're 6 to 8 inches long, though they continue growing if left in the ground. Check maturity by gently uncovering the shoulder of the root to see its diameter; harvest before the first hard freeze to ensure the best texture and flavor.
