Introduction
Winter cabbage (Brassica oleracea) is a hardy vegetable that thrives in cooler temperatures, making it an excellent choice for autumn planting. By sowing winter cabbage in October, you can enjoy fresh, nutritious heads throughout the winter and early spring. This comprehensive guide will walk you through everything you need to know about growing winter cabbage in October, from selecting the best varieties to harvesting your crop. With our expert tips, you’ll be well on your way to a successful and rewarding gardening experience.
Why Plant Winter Cabbage in October
Cold-Hardy Crop
Winter cabbage is specifically bred to withstand cold temperatures and even light frosts. Planting in October allows the plants to establish themselves before the onset of severe winter weather.
Extended Harvest Season
By planting winter cabbage in October, you can enjoy a harvest from late winter through early spring when fresh vegetables are scarce.
Nutritional Benefits
Cabbage is rich in vitamins C and K, fiber, and antioxidants. Growing your own ensures you have access to fresh, nutrient-dense produce during the colder months.
Pest and Disease Reduction
Cooler temperatures in autumn reduce the activity of many common pests, resulting in healthier plants and a more abundant harvest.
Choosing the Right Winter Cabbage Varieties
Selecting the appropriate winter cabbage variety is crucial for successful autumn planting. You’ll want to choose types that are cold-hardy and can mature during the winter months.

Preparing Your Garden for Planting
Site Selection
- Sunlight: Cabbage prefers full sun but can tolerate partial shade.
- Soil Type: Well-drained, fertile soil with a pH between 6.0 and 7.5 is ideal.
- Previous Crops: Avoid planting cabbage where other brassicas (like broccoli, kale, or cauliflower) have recently grown to prevent disease buildup.
Soil Preparation
- Clear the Area
- Remove weeds, rocks, and debris to reduce competition and ensure healthy growth.
- Soil Testing
- Conduct a soil test to determine pH and nutrient levels.
- Amend the soil accordingly to achieve the optimal pH.
- Soil Amendment
- Incorporate organic matter such as compost or well-rotted manure to enhance soil fertility and structure.
- Cabbage is a heavy feeder and benefits from nutrient-rich soil.
- Improving Drainage
- In heavy clay soils, consider adding sand or perlite.
- Raised beds are excellent options for better drainage and soil control.
Crop Rotation
- Practice Crop Rotation: To prevent disease and pest issues, avoid planting cabbage where other brassicas have recently grown.
How to Plant Winter Cabbage in October
Materials Needed
- Winter cabbage seedlings or seeds (cold-hardy varieties)
- Garden fork or spade
- Rake
- Trowel
- Organic fertilizer (optional)
- Horticultural fleece or cloches (for protection)
- Labels (optional)
Planting Methods
You can choose between planting seedlings or sowing seeds directly outdoors.
Planting Seedlings
Step-by-Step Guide
- Prepare the Soil
- Dig the soil to a depth of 30 cm (12 inches).
- Incorporate compost or well-rotted manure.
- Spacing
- Space plants 45-60 cm (18-24 inches) apart in rows 60 cm (24 inches) apart.
- Allow enough space for the mature size of the variety.
- Planting
- Dig a hole large enough to accommodate the root ball.
- Place the seedling in the hole, burying it up to the first set of true leaves.
- Firm the soil around the base.
- Watering
- Water thoroughly to settle the soil.
- Mulching
- Apply a layer of organic mulch to conserve moisture and regulate soil temperature.
- Protection
- Use horticultural fleece or cloches to protect young plants from pests and frost.
Direct Sowing Seeds Outdoors
Step-by-Step Guide
- Prepare the Soil
- Rake the soil to a fine tilth.
- Sow the Seeds
- Depth: Sow seeds at a depth of 1 cm (0.5 inches).
- Spacing: Sow seeds thinly in drills 15 cm (6 inches) apart.
- Cover and Firm
- Gently cover the seeds with soil and firm down lightly.
- Watering
- Water the area gently to settle the soil.
- Thinning
- Once seedlings have emerged and have two true leaves, thin them to 45-60 cm (18-24 inches) apart.
- Protection
- Use horticultural fleece or cloches to protect seedlings from pests and frost.
Indoor Sowing for Transplanting Later
If you prefer, you can start seeds indoors in trays or modules and transplant them outdoors when they are sturdy enough.
Caring for Your Winter Cabbage Plants
Watering
- Consistent Moisture
- Keep the soil consistently moist but not waterlogged.
- Water deeply to encourage strong root development.
- Watering Tips
- Water at the base of the plants to keep foliage dry.
- Use a soaker hose or drip irrigation for even moisture.
Fertilizing
- Soil Fertility
- Cabbage benefits from additional feeding due to its heavy nutrient requirements.
- Apply a nitrogen-rich fertilizer when plants are established and again midway through the growth cycle.
- Avoid Over-Fertilization
- Excessive nitrogen can lead to leafy growth with smaller heads.
- Follow recommended application rates.
Weed Control
- Keep the area weed-free to reduce competition.
- Hand-weed carefully to avoid disturbing the shallow roots.
Mulching
- Apply a layer of organic mulch to conserve moisture and suppress weeds.
- Mulch also helps regulate soil temperature.
Staking
- Larger varieties may require staking to support heavy heads.
- Use bamboo stakes or garden canes, tying the stem loosely with garden twine.
Protection
- Frost Protection
- Winter cabbage is cold-hardy, but young plants may need protection.
- Use horticultural fleece or cloches during severe frost.
- Pest Protection
- Netting can help protect against birds and insects.

A: Splitting occurs when cabbages take up excess water after maturity. To prevent this:
- Harvest promptly when heads are firm.
- Reduce watering as heads reach maturity.
- Twist the plant slightly to break some roots and reduce water uptake.
Q5: Do I need to fertilize cabbage?
A: Yes, cabbage is a heavy feeder. Regular fertilization with a nitrogen-rich fertilizer promotes healthy growth. Avoid over-fertilizing to prevent excessive leaf growth.
