Planting Instructions for Copenhagen Market Cabbage Seeds
Copenhagen Market cabbages are a hardy, biennial, cool-season crop, growing best where the summers are mild. Early maturing heirloom cabbage varieties are planted in the spring, and longer season heirloom varieties are usually planted in summer for a fall harvest. Start spring cabbage varieties indoors 6-8 weeks before last frost or direct seed in full sun. Plant seeds ¼-½” deep, 4-6″ apart, in rows 2-3′ apart. Germination usually occurs in 5-17 days in soil 55-75°F. Thin heirloom cabbage plants to or set out transplants 15-24″ apart. Harvest early cabbage varieties promptly to avoid bursting, later types will hold in the field longer. At harvest, keep 2-3 wrapper leaves to protect heirloom cabbage heads from bruising.
