Characteristics:
Late Flat Dutch cabbage is a longtime standard for late-season harvests. This variety is known for its large, flat heads that are solid and heavy, making it ideal for kraut and long storage. Late Flat Dutch offers excellent flavor and holds up well after harvest, making it a top choice for both fresh use and processing. Its dependable performance and keeping quality have made it a staple in home gardens and on farms for generations.
Cabbage (Brassica oleracea var. capitata)
Cabbage is a cool-season vegetable suited to both spring and fall. It belongs to the cole crop family (Brassica oleracea), which includes broccoli, Brussels sprouts, cauliflower, collards, kale, and kohlrabi. The trick to growing cabbage is steady, uninterrupted growth. That means rich soil, plenty of water, and good fertilization.
Temperature
Cabbage and related brassicas are heavy feeders. They require fertile soils in a pH range of 6.5–7.5, supplied with consistent irrigation throughout the growing period.
- EARLY SPRING CROP: Mid-season and early varieties are used. Sow 2 seeds per cell in 50–72 cell plug flats, 3–4 seeds/in. in 20-row flats, or outdoor beds 1/4" deep. Seedlings should be ready to transplant in 4–6 weeks. Keep soil temperature over 75°F until germination, then reduce air temperature to about 60°F. Transplant outdoors 4–6 weeks after sowing, 12–18" apart in rows 18–36" apart. Cabbage prefers cooler growing temperatures, between 55–75°F, the optimum being 60–70°F, but will produce good crops under warmer, summer conditions.
- FALL CROP: Choose mid-season and storage varieties. Start seedlings as above in May and transplant to the garden in June–July. 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 in mild winters (rarely below 32°F). Transplants can be set out from September to February in these regions.
Direct Seeding & Spacing
Sow 3–4 seeds 12" apart, 1/2" deep, rows 24–36" apart, thinning to one plant in each group.
Splitting
Early varieties may split or burst at maturity or from rapid new growth if rain or heavy irrigation follows a dry spell. Splitting may be partially avoided by slowing a plant's growth. To accomplish this, cultivate close to plants to sever some of the root system or slightly twist the plant.
Diseases
Adhere strictly to a preventive program including:
- Long crop rotations with non-cruciferous crops
- Clean starting mixes and outdoor seedbeds
- Strict sanitation practices
Harvest and Storage
Relatively young heads (still green and actively growing) store best. Ideal conditions are 32°F, at 95–98% relative humidity, with good air circulation. Store heads that are disease-free. From cool weather, spring transplanting, subtract 10–14 days for late spring or early summer, warm weather transplanting. Add about 14 days for direct seeding.
