- Best planted in rich, moist soil, with well-rotted compost tilled in.
- Does best in full sun and tolerates light frosts.

- Keep soil moist and fertilize when heading begins.
- Slugs are a common pest. Also be vigilant for pests like the cabbage root fly and the cabbage white butterfly. Row covers work well to protect against pests.
- Also susceptible to fungal, bacterial, and viral diseases including club root, downy mildew, powdery mildew, and various mosaic viruses.
- Select your best plants to keep for seed and leave them to flower and go to seed.
- Leave plants in the ground over winter, with heavy mulch and a row cover in harsh winter areas.
- In the second season, the plant will send up flower stalks from the head, and as they mature they will become seed pods.
- Once the seed stalks/pods are brown and dry, cut the seed stalks off, and break open the seed pods with your hands or a rolling pin over a container such as a bowl or plate, and separate and extract the seeds.
