When to Plant Cabbage Seeds

Cabbage seeds can be sown indoors or outdoors, depending on the time of year and your gardening goals. For early crops, sow seeds indoors from January to March, then transplant seedlings outdoors from March to May. Alternatively, you can sow seeds directly in the garden from April to July for summer and autumn harvesting. For winter cabbages, sow seeds in a seedbed outdoors from April to June and transplant them to their final growing positions in June or July.

How to Grow Cabbage from Seed

To grow cabbage from seed, start by sowing seeds in seed trays or modules filled with a good-quality seed compost. Cover the seeds lightly with compost and keep them moist but not waterlogged. Place the trays in a bright, cool location with a temperature of around 10-15°C. Once the seedlings have grown large enough to handle and have at least two true leaves, transplant them into individual pots or directly into their final growing positions in the garden. Space the plants about 30-45cm apart, depending on the variety, and leave 45-60cm between rows. Choose a sunny spot with fertile, well-drained soil that has been enriched with plenty of compost or well-rotted manure. Cabbage benefits from regular watering, particularly during dry spells, and should be mulched to retain moisture and keep weeds at bay. Protect your cabbage plants from pests such as cabbage white butterflies and slugs by using netting or organic slug deterrents.

How Long Does It Take to Harvest Cabbage?

The time to harvest cabbage depends on the variety and growing conditions, but most cabbages are ready to harvest within 12 to 20 weeks of sowing. Early varieties tend to mature faster, while larger winter cabbages take longer to develop. Harvest the cabbages when the heads are firm and well-formed. Cut the head at the base, leaving the outer leaves and roots in the ground to encourage further growth, as some varieties will produce a second, smaller crop of heads. Cabbage can be harvested as needed, with winter cabbages often left in the ground until required, as they are frost-hardy and can withstand cold weather.

Why Grow Cabbage from Seed?

Growing cabbage from seed offers several advantages, including access to a broader range of varieties that may not be available as seedlings. Whether you’re looking for early, mid-season, or late varieties, starting from seed allows you to select the best types for your garden and culinary needs. Growing from seed is also more economical, especially if you plan to grow a significant number of plants or experiment with different types. By starting from seed, you can control the growing conditions from the outset, ensuring strong, healthy plants that are well-adapted to your garden's environment. Additionally, there is great satisfaction in nurturing a crop from seed to harvest and enjoying the fresh, flavourful results.

Where Can You Grow Cabbage?

Cabbage is a versatile crop that can be grown in traditional garden beds, raised beds, or large containers. It thrives in full sun and prefers well-drained, fertile soil rich in organic matter. Cabbage can tolerate cooler temperatures, making it suitable for early spring or late autumn planting. It is an excellent companion for other brassicas like broccoli, Brussels sprouts, and kale, as well as herbs such as dill and chamomile, which can help repel pests. Cabbage is also well-suited to crop rotation schemes, helping to maintain soil fertility and reduce the risk of disease.
