Where Can You Grow Mizuna?

Mizuna prefers full sun to part shade and well-drained, fertile soil. Best planted in cooler months—autumn, winter, and early spring—for continuous harvest. Sow seeds 6 mm deep and space plants ~15–25 cm apart in rows. Succession sow every few weeks to prolong harvest and prevent bolting.
