Cabbage  - Key Growing Information

Cabbage is a versatile and nutritious vegetable that can be a rewarding addition to any garden. This guide will provide you with the best methods to grow cabbage, including tips on planting, spacing, watering, and choosing the right varieties. Whether you're a beginner or an experienced gardener, these tips will help you achieve a bountiful harvest.

Scientific Name

Brassica oleracea var. capitata

Crop Culture

Cabbage, a cool-season crop, thrives in full sun and prefers fertile, well-drained soil with a pH of 6.0-7.5. Enrich the soil with compost or well-rotted manure before planting. Cabbage is sensitive to temperature; extreme cold or heat can affect head formation.

  • Planting Time: For spring planting, start seeds indoors 6-8 weeks before the last frost date. Transplant seedlings outdoors when they have 3-4 true leaves, typically 2-3 weeks before the last frost date. For a fall harvest, sow seeds in mid-summer.

Planting Cabbages

Proper spacing and planting are crucial for healthy cabbage growth.

  • Spacing: Space plants 12-24 inches apart in rows 24-36 inches apart, depending on the variety and size of the cabbage heads you are growing. This allows each plant enough space to grow and ensures good air circulation, which helps prevent diseases.
  • Depth: Plant seeds about 1 cm deep in seed trays or pots, and transplant them into the garden when they are 10-15 cm tall and the soil has warmed up.
  • Watering: Water consistently to keep the soil moist but not waterlogged. Mulching helps retain soil moisture and control weeds.
  • Direct Sowing vs. Module Sowing: Cabbage can be sown directly into the ground or started in modules. Module sowing is often preferred as it allows better control over growing conditions and easier management of pests and diseases. Direct sowing can save time and is suitable if you have good soil conditions.

Soil and Watering

Cabbage prefers well-drained soil rich in organic matter.

  • Soil Preparation: Work compost or well-rotted manure into the soil before planting to improve fertility.
  • Watering: Keep the soil consistently moist but not waterlogged. Watering regularly helps prevent bolting (premature flowering) and ensures even plant development. Mulching can help retain moisture and suppress weeds.

Recommended Varieties

Choosing the right variety can enhance your growing experience and yield. Here are some cabbage varieties that are good for solving common problems and avoiding diseases:

Variety Description Benefits
'Kalibos Red' Sweet flavor, pointed heads Attractive color, good disease resistance
'Red Drumhead' Deep red, firm heads Good for storage, resistant to splitting
'Ormskirk' Traditional variety with large, round heads Reliable yields, good flavor
'Wheelers Imperial' Early maturing, compact heads Cold-tolerant, reliable performance
'Dutchman F1' Uniform, dense heads Excellent disease resistance, high yield
'Deacon F1' Large, dense heads Good storage ability, disease resistant
'Sunta F1' Early maturing, compact heads Good flavor, consistent yields
'Golden Acre' Early maturing, small heads Good flavor, reliable yields

Preventing Common Problems

Certain varieties and cultivation methods can help prevent or reduce common problems associated with growing cabbage.

  • Avoiding Bolting: Choose bolt-resistant varieties like 'Wheelers Imperial' and ensure consistent moisture levels. Avoid stress conditions such as irregular watering and extreme temperatures.
  • Pest Control: Common pests include cabbage loopers, aphids, and flea beetles. Use row covers to protect young plants and apply organic or chemical pest controls if necessary.
  • Disease Management: Diseases like clubroot and black rot can be prevented with crop rotation and proper spacing. Ensure good air circulation to prevent fungal diseases like downy mildew and clubroot.

Harvesting Cabbage

Knowing when and how to harvest cabbage is crucial for the best flavor and yield.

  • Harvest Time: Cabbage is typically ready to harvest 70-120 days after sowing, depending on the variety.
  • Signs of Readiness: The heads should be firm and tightly packed. They should feel solid when squeezed.
  • Harvesting Method: Use a sharp knife to cut the head from the stem at the base. If the weather is warm, harvest in the morning when the heads are cool. Smaller side heads may develop after the main head is harvested, extending the harvest period.

Storage and Preservation

  • Short-Term Storage: Cabbage can be stored in a cool, humid place for several months.
  • Long-Term Storage: For longer storage, it can be fermented to make sauerkraut or kimchi, or it can be blanched and frozen for use in cooked dishes.

Growing Cabbage in Containers

Cabbage can also be grown successfully in containers, making them perfect for small spaces such as balconies.

  • Container Size: Use a pot that is at least 30 cm in diameter and depth.
  • Soil: Use a high-quality potting mix enriched with compost.
  • Watering: Keep the soil evenly moist and ensure the container has good drainage.

By following these guidelines and choosing the right varieties, you can enjoy a plentiful harvest of delicious cabbage. Whether you have a large garden or just a small balcony, cabbage is a rewarding and versatile crop to grow.
