Cabbage (Brassica oleracea var. capitata) is an excellent choice for home gardeners. It is simple to cultivate and harvest, with attractive ornamental features that enhance any landscape. Furthermore, it is versatile in the kitchen, being a key ingredient in a variety of dishes from hearty meals like corned beef and cabbage to lighter options like coleslaw. Many cabbage varieties do well in USDA zones 1 through 9, making them a low-maintenance vegetable that can withstand colder temperatures. With adequate sunlight and nutrient-rich soil, cabbage plants will produce a plentiful yield.

Selecting the Right Cabbage Type:
There are numerous cabbage varieties within the Brassica oleracea family, each suited to different USDA hardiness zones. Consult your local plant nursery or extension service for guidance before purchasing cabbage seeds. Some favorite varieties recommended by our experts include Black cabbage, Choy sum cabbage, Green cabbage, January king cabbage, Red cabbage, Savoy cabbage, Napa cabbage, Bok choy, and Leaf cabbage.
Planting Cabbage:
The timing for planting cabbage varies depending on the type. “Generally, seeds are planted 6 to 8 weeks before the last frost for spring crops, or in mid-summer for fall harvests,” advises Valeria Nyman. Cabbage is typically a cool-season vegetable, but in areas with mild winters, seeds can be sown in early fall for a winter crop. In colder regions, fall planting with protection is possible, but spring planting is recommended, notes Christy Wilhelmi.
How to Plant Cabbage:
Cabbage can be grown from seed directly in the ground or by transplanting seedlings purchased from a nursery.
Planting from Seed:
– Sow cabbage seeds directly into well-draining soil, spacing them 18 to 24 inches apart.
– Ensure the soil is loosened and mixed with compost before planting.
– Water regularly and add compost every few weeks after planting.
Transplanting Seedlings:
– Dig a hole in well-draining soil, place the root ball in the hole, and backfill with soil.
– Water the soil frequently to maintain consistent moisture.
Caring for Cabbage:
To ensure healthy cabbage plants, provide them with optimal growing conditions.
Sunlight:
Cabbage thrives with at least six hours of direct sunlight daily, though some shade is acceptable in hot climates.
Plant experts recommend keeping cabbage plants’ soil consistently moist to prevent split heads and ensure a good flavor. However, it’s important not to overwater, as this can lead to root rot. Aim to provide about 1 inch of water per week, watering a little each morning to maintain moisture levels. Ideal soil for cabbage is loamy and well-draining, with a pH between 6.5 to 6.8. Cabbage thrives in cooler temperatures between 55 to 75 degrees Fahrenheit. It’s beneficial to fertilize monthly with an organic vegetable fertilizer and supplement with compost or worm castings. Starting cabbage seeds indoors is an option, and transplanting should be done carefully to avoid root disturbance. Harvest cabbage when the head feels firm and store in a cool place. Protect cabbage from common pests like cabbage moths by covering with a floating row cover. Diseases like clubroot and black rot can be prevented through proper rotation practices.
“Ensuring the health of your crops and maintaining proper soil drainage is crucial,” advises Sons. “To prevent diseases from affecting your cabbage, it is essential to test the pH balance of your soil and aim to keep it around 7.0 for optimal results.”
When it comes to dealing with aphids, common pests that pose a threat to cabbage plants, there are various preventive measures that can be taken. One effective method is to use floating row covers to shield the plants from aphids, or alternatively, manually remove the pests by hand. Another approach is companion planting, where vegetables, herbs, or flowers such as marigolds are grown alongside cabbage to repel aphids, as suggested by Nyman.
