When to Plant Red Cabbage

1. Spring Planting
   • Start Seeds Indoors: 6–8 weeks before the last expected frost date.
   • Transplant Outdoors: Once seedlings have 4–5 true leaves and temperatures are consistently above 45°F (7°C).
2. Fall Planting
   • Direct Sowing: Sow seeds 4–6 weeks before the first expected frost.
   • Transplanting: Start seeds indoors in early summer and transplant in mid-to-late summer for autumn harvest.
3. Winter Growing (Mild Climates)
   • In regions with mild winters, red cabbage can be planted in late autumn for overwintering and early spring harvest.

Preparing the Soil

1. Soil Type
   • Well-Drained: Prevents root rot and other water-related diseases.
   • Loamy Soil: Rich in organic matter, ensuring fertility and good structure.
2. pH Level
   • Slightly acidic to neutral (6.0–7.5) is ideal for optimal growth and color intensity.
3. Soil Enrichment
   • Incorporate compost or well-rotted manure to enhance soil fertility.
   • Add a balanced fertilizer (e.g., 10-10-10) before planting and as needed during growth.

How to Plant Red Cabbage

1. Starting Seeds Indoors
   • Containers: Use seed trays or small pots filled with seed-starting mix.
   • Sowing Depth: Plant seeds 1/4–1/2 inch deep.
   • Germination Conditions: Keep the soil moist and maintain a temperature of 65–75°F (18–24°C).
2. Transplanting Seedlings
   • Spacing: Space plants 12–18 inches apart in rows 18–24 inches apart.
   • Hardening Off: Gradually expose seedlings to outdoor conditions over 7–10 days before transplanting.
3. Direct Sowing
   • Timing: Sow seeds directly in the garden in early spring or mid-to-late summer for fall harvests.
   • Spacing: Follow the same spacing guidelines as transplanting.
4. Watering After Planting
   • Water thoroughly to settle the soil around the roots and eliminate air pockets.

Caring for Red Cabbage

1. Watering

• Consistent Moisture: Keep the soil evenly moist, providing 1–1.5 inches of water per week.
• Avoid Overwatering: Prevents root diseases and ensures healthy growth.

2. Fertilizing

• Balanced Fertilizer: Apply every 3–4 weeks with a balanced formula (10-10-10) or use compost.
• Nitrogen-Rich Feed: Supports leafy growth, essential for forming firm heads.

3. Mulching

• Moisture Retention: Helps retain soil moisture and regulate temperature.
• Weed Suppression: Reduces competition for nutrients and space.

4. Pest and Disease Management

• Regular Inspection: Check plants weekly for signs of pests or diseases.
• Row Covers: Use to protect against insects like cabbage worms and aphids.
• Natural Remedies: Apply neem oil or insecticidal soap as needed.

Common Pests and Diseases

Pests

• Cabbage Worms and Loopers
  • Control Methods: Handpick larvae, use Bacillus thuringiensis (Bt), or apply neem oil.
• Aphids
  • Control Methods: Spray with water, apply insecticidal soap, or introduce beneficial insects like ladybugs.
• Flea Beetles
  • Control Methods: Use row covers, apply diatomaceous earth, or employ neem oil.

Diseases

• Clubroot
  • Prevention: Rotate crops, use well-drained soil, and plant disease-resistant varieties.
• Black Rot
  • Prevention: Avoid overhead watering, remove infected plants, and ensure good air circulation.
• Powdery Mildew
  • Prevention: Ensure adequate spacing for airflow, use fungicidal sprays if necessary.

Harvesting Red Cabbage

1. When to Harvest
   • Firm Heads: Harvest when heads are firm, compact, and have reached their mature size, typically 70–100 days after planting.
   • Color Intensity: Deeper red hues indicate maturity, though some varieties may retain more green.
2. How to Harvest
   • Cutting the Head: Use a sharp knife to cut the head at the base, leaving some outer leaves if desired.
