Soil & site
Rich soil with plenty of nitrogen — compost generously at planting. pH 6.0–7.0.
Seedling care
Ready to transplant at 4–6 weeks with 4 true leaves. Harden off over 5–7 days, and bury the stem to the first leaves.
Growing notes
The workhorse green. Watch for cabbage worms early; row cover at transplant stops the moths entirely.
Harvest
Pick lower leaves and let the crown keep producing. Flavor sweetens dramatically after hard frost.
