Sowing Cabbage Seeds: The Best Time and Planting Depth for Cabbage in South Africa
Best Time to Sow
For most provinces in South Africa, late winter to early spring (July to September) is the optimal time to sow cabbage seeds. This timing allows the young seedlings to establish themselves before the heat of summer or cold of winter.
Planting Depth
Sow cabbage seeds at a depth of approximately 0.5 cm to 1 cm. Ensure even spacing between the seeds in rows to prevent overcrowding as they germinate.
Proper Plant Spacing and Row Spacing
Plant Spacing in Centimeters (cm)
- Small Cabbage: Space plants 30 cm apart in rows that are 45 cm apart.
- Medium Cabbage: Leave 40 cm between plants, with rows spaced 60 cm apart.
- Large Cabbage: Allow a generous 60 cm between plants and space rows 75 cm apart.
Ensuring adequate spacing promotes healthy growth and minimizes competition for nutrients.
Soil Preparation, Irrigation, and Fertilization
Soil Preparation
Prepare your soil by tilling it to a depth of at least 20 cm. Incorporate well-rotted compost or organic matter to improve soil fertility and structure. Cabbage thrives in well-draining soil with a pH level between 6.0 and 7.5.
Irrigation Frequency
Cabbage in South Africa requires consistent moisture to grow successfully. Provide 1 to 1.5 inches of water per week, either through rainfall or irrigation. It’s crucial to keep the soil consistently moist but not waterlogged.
Fertilizer Requirements
Cabbage benefits from a balanced fertilizer application. Before planting, apply a complete fertilizer such as 10-10-10 at a rate of 2 to 3 pounds per 100 square feet. Side-dress the plants with nitrogen-rich fertilizer when they begin to form heads.
Care and Maintenance of Your Cabbage Crop
Sunlight and Water
Cabbage in South Africa thrives in full sun, so provide at least 6 hours of sunlight daily. Maintain consistent soil moisture by watering evenly, ensuring the soil remains consistently moist, but not waterlogged.
Mulching
Apply mulch around cabbage plants to retain moisture, regulate soil temperature, and reduce weed competition.
Pest Control Throughout the Cabbage Lifecycle
Early Stage (Seedlings)
- Aphids: Monitor young cabbage plants for aphids. Apply insecticidal soap or neem oil as a natural control if necessary.
Mid-Growth (Vegetative Stage)
- Cabbage Worms: Watch for signs of cabbage worms on leaves. Hand-pick them or use Bacillus thuringiensis (BT) as a natural control.
Late Stage (Heading Formation)
- Slugs and Snails: Protect mature cabbage heads from slugs and snails. Use barriers like crushed eggshells or beer traps.
Common Diseases
- Black Rot: Caused by a bacterium, it creates V-shaped lesions on leaves. Practice crop rotation and remove infected plants.
- Clubroot: This fungal disease causes stunted growth and club-shaped roots. Improve soil drainage and use disease-resistant varieties.
Harvesting and Handling Cabbage
Harvesting
Cabbage is ready to harvest when the heads are firm and reach their mature size. Use a sharp knife to cut the cabbage just above the soil surface.
Handling
Handle cabbage heads carefully to avoid bruising. Store them in a cool, dark place or refrigerate them for extended freshness.
Best Storage Practices and Transportation
Storage Circumstances
Cabbage can be stored for weeks if kept in a cool, dark place with high humidity. A root cellar or refrigerator is ideal. Keep cabbage in South Africa away from ethylene-producing fruits to prevent premature ripening.
Transportation and Handling
When transporting cabbage, use crates or containers to prevent bruising and damage. Keep the cabbage cool during transportation to maintain quality.
