Soil & site
Rich, firm, consistently moist soil. Stress at any point risks “buttoning” — tiny premature heads.
Seedling care
Set starts slightly deeper than the pot, up to the first leaves. Water in well and shade for a day if it's hot.
Growing notes
Row cover at transplant blocks cabbage moths. Steady water is non-negotiable for good heads. Rows 24–30 in.
Harvest
Cut the main head while buds are tight, with 5–6 in of stem. Side shoots keep coming for weeks after.
