Thin seedlings to proper spacing when 2-3 inches tall. Keep soil evenly moist. Protect from direct wind and harsh sun initially.
Vegetative Growth

Fun Facts

- 🌱 Daikon radishes can grow quite large—some varieties exceed 12 inches—and the Japanese tradition of 'daikon contest' awards have been given to specimens weighing over 100 pounds, though Shogoin typically stays in the 1-3 pound range.
