Growing spring cabbages starts with sowing seeds now for a fresh harvest next year. If you have space and patience, this rewarding crop can provide delicious greens from your own garden. Let’s explore the best practices for sowing, protecting, and harvesting spring cabbages.
Why Sow Spring Cabbages Now?
Sowing spring cabbages in late summer takes advantage of warm soil and long daylight hours, encouraging quick germination and strong seedling growth. These young plants will then overwinter in the ground, ready to mature as the weather warms in spring. This timing ensures a steady supply of fresh greens when other vegetables are scarce.
Compared to buying supermarket cabbages, homegrown varieties offer superior flavor and texture. Plus, you control the growing conditions, avoiding harmful pesticides. For gardeners with limited space, consider growing compact varieties or interplanting with other crops to maximize efficiency.
Step-by-Step Sowing Guide
1. Choose Quality Seeds and Compost
Start with certified disease-free seeds from a reputable supplier. Use a good quality sowing compost that is moist but well-draining. Fill modular trays or small pots, pressing the compost lightly.
2. Sow Seeds at the Right Depth
Sow seeds about 1 cm deep, placing one or two seeds per module. Cover lightly with compost and water gently. Keep the tray in a sunny spot or under a cold frame, maintaining consistent moisture.
3. Transplanting and Spacing
Once seedlings have two true leaves, transplant them into larger pots or directly into the garden. Space plants 30–40 cm apart to allow ample room for head development. Closer spacing (around 25 cm) yields smaller spring greens, which can be harvested early.
Protecting Your Cabbages from Pests
Brassicas attract a range of pests, including cabbage white butterflies, aphids, and pigeons. Use insect-proof mesh or fine netting to cover young plants, preventing egg-laying and damage. Regularly inspect the undersides of leaves for caterpillars and remove them by hand if necessary.
Companion planting with herbs like thyme or mint can also deter pests. Ensure good air circulation to reduce fungal diseases, and rotate crops annually to avoid soil-borne issues.

| Flavor | Sweet and tender | Mild and crisp |
Key Takeaways for Successful Cabbage Growing
- Sow seeds in modular trays using quality compost for strong root development.
- Provide 6+ hours of sunlight daily and nutrient-rich, well-draining soil.
- Space plants 30–40 cm apart to allow full head formation.
- Use insect-proof mesh to protect against pests like butterflies and pigeons.
- Harvest spring greens early from closely spaced plants, leaving others to mature.
Overwintering and Spring Care
As winter approaches, your cabbage plants will slow down but remain hardy. Mulch around the base to protect roots from freezing temperatures. In early spring, apply a nitrogen-rich fertilizer to boost growth.
Monitor for signs of bolting (premature flowering) if temperatures fluctuate. Water consistently, but avoid waterlogging. With proper care, you’ll enjoy fresh, crunchy cabbages from April to June.
