Heirloom organic cabbage is a cool-season vegetable suited to both spring and fall season. The key to growing great cabbage is st
eady, uninterrupted growth. That means rich soil, plenty of water, and good manure.
Germination: Cabbage seed germination will be poor if soil temperatures are below 50 degrees.
Soil: Surprisingly heirloom organic cabbage will do well on heavy clay soil, although it prefers a rich heavy loam. It delights in copious amounts of composted manure mixed into the soil bed. Remember not to plant cabbage seed in the same place year to year. The soil pH should be between 6.0 and 7.5 for optimum growth and to discourage clubroot disease.
Transplanting Organic Cabbage: Set out your spring cabbage transplants early enough so that they can mature before the heat of summer, about 5 weeks before the last frost. For a longer cabbage harvest plant 2 or 3 varieties with different maturities.
Heirloom cabbage needs even moisture to produce good heads. Mulch cabbage with compost to keep the soil cool and moist. Water regularly, applying 1 to 1.5 inches of water per week if it doesn't rain. Feed cabbage with a liquid fertilizer such as fish emulsion or seaweed combination after they begin to develop new leaves and when they start forming heads.
