Beautiful, delicious red/purple cabbage variety that is quite hardy in a wide variety of growing conditions, even warmer temperatures. Produces 5-8lb heads (8-10″ across) that also make good keepers. Once known as “Red Danish” cabbage.
Cabbage – Mammoth Red Rock – Brassica oleracea var. capitata
Soil & Water: Cabbage prefers rich, fertile soil with a pH of 6.0-7.5. Water heavily from planting to head formation, then water moderately to prevent splitting.
Planting & Growing: Start indoors 8 weeks before last frost, or outdoors March through June. Cabbage prefers cool weather. Fast growing or stressed cabbages tend to split and bolt; cutting into the root system by transplanting will slow growth and prevent splitting. Provide transplants with cutworm shield collars.
Harvesting & Storage: Early types of cabbage grow and mature quickly and must be harvested promptly to avoid splitting. Heads store well in cool (32F-40F), moist locations for 5-6 months. Harvest when the head feels solid. Smaller heads sometimes grow from the remaining plant.
