Choosing the Right Red Cabbage Variety
Selecting the appropriate variety is crucial for success. Consider your climate, growing space, and desired characteristics when choosing a red cabbage cultivar.
| Variety | Days to Maturity | Head Size | Characteristics |
|---|---|---|---|
| Red Acre | 75-85 days | 3-5 lbs | Good storage, resistant to splitting. |
| Red Express | 65-70 days | 2-3 lbs | Early maturing, good for smaller gardens. |
| Ruby Ball | 70-75 days | 3-4 lbs | Sweet flavor, good for salads. |
| Regal Red | 80-90 days | 4-6 lbs | Disease resistant, excellent storage potential. |
The Growing Process: From Seed to Harvest
Cultivating red cabbage requires a step-by-step approach to ensure optimal growth and a successful harvest.
- Starting Seeds (Optional): Begin indoors 6-8 weeks before the last expected frost. Sow seeds ¼ inch deep in seed-starting mix. Keep moist and warm (around 70°F).
- Preparing the Soil: Red cabbage thrives in well-draining soil rich in organic matter. Amend the soil with compost or well-rotted manure. The ideal pH is between 6.0 and 7.0.
- Transplanting Seedlings (or Direct Sowing): Transplant seedlings (or direct sow seeds) after the last frost, spacing plants 18-24 inches apart in rows 24-36 inches apart.
- Watering: Water regularly, especially during dry periods. Red cabbage needs consistent moisture to develop properly. Aim for about 1-1.5 inches of water per week.
- Fertilizing: Feed plants every 2-3 weeks with a balanced fertilizer or side-dress with compost. Nitrogen is essential for leafy growth, but avoid over-fertilizing.
- Weeding: Keep the area around the plants free of weeds, which compete for nutrients and water.
- Pest and Disease Control: Monitor plants regularly for pests and diseases. Take action promptly to prevent infestations from spreading. Common pests include cabbage worms, aphids, and flea beetles.
- Harvesting: Harvest red cabbage when the heads are firm and fully colored. Use a sharp knife to cut the head from the stem.
Common Mistakes to Avoid
Even with careful planning, some common pitfalls can hinder red cabbage growth. Avoid these mistakes:
- Neglecting Soil Preparation: Poor soil can lead to stunted growth and nutrient deficiencies.
- Inadequate Watering: Insufficient water can result in small, loose heads.
- Ignoring Pests and Diseases: Untreated infestations can decimate your crop.
- Over-Fertilizing: Excessive fertilizer can cause bolting (premature flowering) and poor head formation.
- Harvesting Too Late: Overripe cabbage heads can split and become tough.
Storing Your Harvest
Proper storage ensures that your red cabbage remains fresh and flavorful for weeks or even months.
- Cool, Dark, and Dry: Store unwashed red cabbage heads in a cool, dark, and dry place, such as a root cellar or refrigerator.
- Optimal Temperature: The ideal storage temperature is between 32°F and 40°F.
- Wrap in Plastic: To prevent drying out, wrap the cabbage head in plastic wrap or place it in a plastic bag.
Frequently Asked Questions (FAQs)
Why is my red cabbage not turning red?
The vibrancy of red cabbage’s color depends heavily on soil acidity. Alkaline soils can inhibit the plant’s ability to absorb the necessary nutrients for pigment production. Test your soil’s pH and amend it with sulfur or pine needles to lower the pH and encourage a deeper red hue.
How often should I water my red cabbage?
Red cabbage requires consistent moisture, especially during head formation. Aim to water deeply at least 1-2 times per week, providing approximately 1-1.5 inches of water per week. Adjust the watering frequency based on weather conditions and soil moisture.
What are the best companion plants for red cabbage?
Beneficial companion plants can help deter pests and improve growth. Good companions for red cabbage include: aromatic herbs like rosemary and thyme, which repel cabbage moths; marigolds, which deter nematodes; and beans, which fix nitrogen in the soil.
How do I prevent cabbage worms from eating my red cabbage?
Cabbage worms are a common pest that can devastate red cabbage crops. Use row covers to physically prevent moths from laying eggs on the plants. Handpick any worms you find, and consider using Bacillus thuringiensis (Bt), a biological insecticide that is effective against cabbage worms.
Is it better to start red cabbage from seed or buy seedlings?
Both options are viable, depending on your experience and resources. Starting from seed gives you greater control over the variety and growing conditions, but requires more time and effort. Buying seedlings is more convenient and allows you to get a head start, but you have less control over the plant’s history. Consider your individual circumstances and preferences.
What kind of fertilizer should I use for red cabbage?
Red cabbage benefits from a balanced fertilizer, such as a 10-10-10 or 14-14-14, or a fertilizer specifically formulated for vegetables. Apply fertilizer according to the package instructions, being careful not to over-fertilize. Side-dressing with compost throughout the growing season can also provide a slow-release source of nutrients.
How do I know when my red cabbage is ready to harvest?
Red cabbage is ready to harvest when the head is firm and fully colored. Gently squeeze the head; if it feels solid and dense, it’s likely ready. Don’t wait too long, as overripe heads can split and become tough.
Can I grow red cabbage in containers?
Yes, red cabbage can be successfully grown in containers, provided they are large enough (at least 12 inches in diameter) and have good drainage. Use a high-quality potting mix and provide regular watering and fertilization. Container-grown cabbage may require more frequent watering and feeding than those grown in the ground.
What causes red cabbage heads to split?
Splitting can occur due to rapid changes in moisture levels, especially after a period of drought followed by heavy rain. Consistent watering and good soil drainage can help prevent splitting. Choose varieties that are resistant to splitting.
Is red cabbage more difficult to grow than green cabbage?
Red cabbage is generally no more difficult to grow than green cabbage. The growing requirements are similar, and both varieties are susceptible to the same pests and diseases. However, achieving the vibrant red color of red cabbage may require more attention to soil pH.
Can I save seeds from my red cabbage to plant next year?
Saving seeds from red cabbage is possible, but it’s a two-year process. Cabbage is a biennial plant, meaning it flowers and produces seeds in its second year. You’ll need to overwinter the plant and allow it to flower the following spring. However, keep in mind that cross-pollination can occur, resulting in offspring that may not be true to type.
Why are the leaves on my red cabbage turning yellow?
Yellowing leaves can indicate several issues, including nutrient deficiencies, overwatering, or disease. Check the soil pH and nutrient levels. Ensure the soil has good drainage and avoid overwatering. If disease is suspected, consult a local gardening expert or agricultural extension office for identification and treatment options. Early intervention is key to resolving the problem.
