Temperatures are under 80 F. High fertility, improper water conditions, and heat can cause loose, puffy heads. Spring planting should occur as soon as soil can be worked, 3 to 5 weeks before last frost, and fall planting done around June or July. Plants can grow 6 to 12″ tall.
sprout Growing Cabbage
While perhaps not one of the most popular vegetables growing in the garden, cabbage is one of the more dependable. Extremely hardy, this member of the brassica family is a cool season biennial grown as an annual.
sprout Site Preparation :
Cabbage requires regular water, full sun to partial shade, and fertile, well-drained soil. If possible, avoid growing cabbage in spots where other brassicas grew the previous three years.
sprout How to Plant :
Plant cabbage in early spring or fall for best results. Plant seed indoors in flats early in the season. Transplant into the garden when two sets of true leaves develop. Allow approximately 15 inches between plants and 2-3 feet between rows. If planting from seed, sow directly into the garden about 1/2 inch deep and two weeks before the last expected frost date. Cabbages are heavy feeders and are susceptible to many nutrient dificiencies. Apply balanced, organic fertilizers every 2-3 weeks.
Seed Saving Instructions:
Biennial. Cabbage will cross-pollinate with all other Brassica oleracea, isolate by one mile the second year when going to seed. In early spring, of the second growing season, cut a shallow “X” in the top of the head. This will allow the emerging seed stalk to push up through the cabbage a bit more easily. The seed stalk actually pushes the head open and uncurls itself as it rises out of the head. It is a vegetable birth in the most graphic sense. The stalk will grow 3-4 inches tall before branching out. Cabbage seeds do not normally require much processing.
