SOWING: Requires heavy fertilization. Cabbage require fertile soils in a pH range of 6.5-7.5, supplied with consistent irrigation throughout the growing period.
EARLY SPRING CROP: Use early and midseason varieties. Sow 2 seeds per cell 1/4″ deep. Seedlings should be ready to transplant in 4-6 weeks. If possible keep soil temperature over 75°F until germination, then reduce air temperature to about 60°F. Transplant outdoors, 12-18″ apart in rows 18-36″ apart. Cabbage prefers cooler growing temperatures, between 55-75°F, but will produce decent crops under warmer, summer conditions.
FALL CROP: Use midseason and storage varieties. Start seedlings late spring and transplant to the garden in early summer. To ensure mature heads, seed the crop early in areas where heavy freezes occur early in fall.
WINTER CROP: Successful cabbage crops can be grown where winters are mild. Transplants can be set out from September to February in these regions.
DIRECT SEEDING: Sow 3-4 seeds 12″ apart, 1/2″ deep, rows 24-36″ apart, thinning to one plant in each group.
HARVEST AND STORAGE: Relatively young heads (still green and actively growing) store best. Ideal conditions are 32°F at 95% relative humidity, with good air circulation.
DAYS TO MATURITY: See each variety for maturity rate from transplanting.
AVG. PRECISION SEEDING RATE: 100 seeds/50′, 500 seeds/250′, 1M/500′, 29M/acre at 2 seeds/ft. with rows 36″ apart.
