Growing Guide

When to Grow

Brunswick cabbage is best grown in the cooler seasons. Start seeds indoors 6-8 weeks before the last expected frost date in your area. For fall harvest, count back from your first expected frost: the 90 days to maturity plus a 6-8 week seedling stage means sowing about 19 to 21 weeks (132-146 days) ahead, in late spring to early summer. The plant is frost-tolerant, so it can survive light frosts, making it ideal for late-season planting. If you're not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Start seeds 1/4 inch deep in seed-starting trays. Keep the soil consistently moist and provide good light. Once seedlings have 2-3 leaves and after the risk of frost has passed, transplant them outdoors, spacing plants 18-20 inches apart in rows 24-36 inches apart. You can also direct sow seeds 1/4 inch deep in well-prepared soil outdoors.

How to Grow

Cabbage thrives in rich, well-drained soil with a pH of 6.5 to 7.0. Provide consistent moisture to avoid splitting heads. Cabbage requires regular watering, especially during dry periods. Use a balanced fertilizer when planting, then side-dress with a nitrogen-rich fertilizer every few weeks. Full sun is ideal, although some afternoon shade can be beneficial in hotter climates.

How to Save Seeds

  • If you plan to save seeds, isolate plants from other members of the cabbage species (kale, collards, broccoli, Brussels sprouts and cauliflower) by up to one mile to avoid cross pollination.
  • Cabbage is biennial, blooming only after experiencing a winter's chill, and will require overwintering with heavy mulch and row cover in cool winter areas.
  • For those with very harsh winters, consider digging up and placing in a root cellar until hard frost has passed.
  • In the second season, when flowers have passed and seed pods have dried, dig up the plants and hang upside down to dry.
  • Dried pods can be placed in a sack and crushed to release seeds. Remove chaff and detritus.
  • Place seeds in a glass jar and refrigerate for up to 5 years.
