Observe plants daily as maturity approaches. Use days since transplanting as baseline. Almost all varieties will be ready for harvest between 60 and 100 days after planting. Check the wrapper leaves to ensure a deep green color and a tight formation. Damaged or yellowing leaves indicate stress issues.
Harvesting during cool temperatures in the early morning will be ideal. Use sharp, well-sanitized knives to make clean cuts. Leave two to four outer leaves intact to protect the heads naturally. Handle heads carefully to prevent bruising and deterioration. Bruises from mishandling will significantly reduce the storage life.
Store cabbage properly to keep it fresh and crisp. Refrigerating whole heads in plastic will keep heads fresh for 3 to 4 weeks. Keeping whole heads in root cellars will keep them fresh for up to 4 months. Store heads root side up to conserve moisture. Keep cabbage away from ethylene-producing fruits like apples.
