Bonnie’s best cabbage grows large, round, flavorful blue-green heads. Well suited to the South as a spring and fall cabbage and in the North as a summer cabbage.
Resistant to Fusarium yellows and tolerant of black rot.
- Light Full sun
- Head size 5 to 7 pounds
- Matures 75 days
- Plant spacing 24 inches apart
- Plant size 18 inches tall, 24 inches wide
Planting: Space 18 to 24 inches apart, depending on type. (Read the stick tag that comes with the plant for specific spacing recommendations.)
Soil requirements: Provide well-drained, nutrient-rich soil that’s high in organic matter. Work 3 or more inches of organic matter into planting beds.
Water requirements: Keep soil consistently moist throughout the growing season. Typically, established cabbage plants need 1 to 1.5 inches of water per week—supplied through rainfall or irrigation. Add mulch to help maintain consistent soil moisture.
Frost-fighting plan: Cabbage tolerates hard frosts (below 28ºF). Cabbages that experience hard freezes won’t store as well, though, so harvest before temps dip below 28ºF if you plan to store heads in a refrigerator or root cellar for any length of time.
Harvesting: Harvest heads when they’re firm and feel solid. Immediately harvest any heads that crack or split. Cut heads from the base of the plant.
Storage: Refrigerate unwashed heads in a plastic bag for up to 2 weeks. Flavor and odor become stronger as storage progresses. Use Savoy cabbage within a few days of harvest.
The trick to growing cabbage is steady, uninterrupted growth. That means rich soil, plenty of water, and good fertilization.
Quick Guide to Growing Cabbage
- Plant spring cabbage 4 weeks before the last frost.
- Space your cabbage according to the guidelines on the plant tag, in an area that gets 6 or more hours of sun. Plant 1 to 2 inches deep in well-drained, fertile soil with a pH of 6.5 to 6.8.
- Improve native soil conditions by mixing in several inches of compost or other rich organic matter.
- Protect new plants from cold weather by planting them through black plastic, which will help keep the soil warm.
- Water regularly by giving plants 1 to 1.5 inches of water weekly.
- Before planting, give cabbage a continuous food supply by mixing a slow-release plant food into the soil.
- Lay down a 3-inch layer of mulch to help retain moisture and keep weeds at bay.
- Harvest cabbage when the head is firm.
