While not as sensitive to heat and cold as Chinese cabbage, spring crops may bolt prematurely if young plants are exposed to frost or a week of nighttime temperatures below 50 F. Wait until after last frost date to direct seed or transplant out.

Start transplants inside 4 to 6 weeks before last frost date. Transplant 6 to 12 inches apart in rows 18 to 30 inches apart. Use the closer spacings for smaller varieties.

Plant direct-seeded spring crops ¼ to ½ inch deep and about 1 inch apart in rows 18 to 30 inches apart. Thin to 6- to 12-inch spacings. Use thinnings in salads.

For fall crops, direct seed ¼ to ½ inch deep in rows 18 to 30 inches apart in summer. Thin to 6- to 12- inch spacings. Or set transplants out at 6- to 12-inch spacings 4 to 6 weeks before first frost.

Mulch fall crops heavily and provide adequate moisture to avoid premature bolting.
