PLANTING INSTRUCTIONS

Oxheart cabbage, known for its unique heart-shaped heads, is a delicious and versatile vegetable that can be used in a variety of dishes. Its dense, tender leaves are perfect for salads, slaws, and cooking. Oxheart cabbage is a cool-season crop that thrives in moderate temperatures and can be grown in both spring and fall. With the right care, you can enjoy a bountiful harvest of this distinctive cabbage. This guide will help you cultivate healthy, productive Oxheart cabbage plants.

• Best Time to Plant:

  Oxheart cabbage is best planted in early spring or late summer for a fall harvest. For spring planting, start seeds indoors 6-8 weeks before the last expected frost date. Transplant seedlings outdoors 2-3 weeks before the last frost. For a fall harvest, sow seeds directly in the garden 10-12 weeks before the first expected frost.

• Soil Type:

  Cabbage thrives in well-drained, fertile soil rich in organic matter. The ideal soil pH for cabbage is between 6.5 and 7.5. Before planting, amend the soil with compost or well-rotted manure to enhance fertility and improve soil structure. Cabbage prefers soil that retains moisture but drains well to prevent waterlogging.

• Spacing:

  Proper spacing is crucial for healthy growth and maximum yield. Plant Oxheart cabbage seedlings 18-24 inches (45-60 cm) apart in rows that are 24-36 inches (60-90 cm) apart. This allows adequate airflow between plants, reducing the risk of disease and encouraging healthy growth.

CARE TIPS

• Watering:

  Consistent moisture is essential for growing healthy cabbage. Water the plants deeply and regularly, aiming for about 1-1.5 inches (2.5-4 cm) of water per week. Mulching around the plants helps retain soil moisture, suppress weeds, and keep the roots cool. Avoid overhead watering to reduce the risk of foliar diseases.

• Fertilizing:

  Cabbage is a heavy feeder and benefits from regular fertilization. Apply a balanced fertilizer, such as 10-10-10, at planting time and then every 3-4 weeks during the growing season. Side-dressing with compost or organic fertilizers can also provide a steady nutrient supply.

• Pruning:

  Pruning is not typically necessary for cabbage, but you should remove any yellowing or damaged leaves to improve air circulation and reduce the risk of disease. This also helps the plant direct more energy towards head development.

HARVESTING

• When to Harvest:

  Oxheart cabbage is usually ready to harvest 70-85 days after planting, depending on growing conditions. Harvest the heads when they are firm and have reached the desired size, typically about 6-8 inches (15-20 cm) in diameter. The heads should be dense and compact.

• How to Harvest:

  Use a sharp knife to cut the cabbage head from the plant, leaving a few outer leaves attached to protect the head. Handle the cabbage gently to avoid bruising. Regular harvesting encourages the plant to produce side heads, providing additional yield.

TROUBLESHOOTING

• Common Issues:

  •Cabbage Worms: Green caterpillars that chew holes in leaves and can damage developing heads.

  •Aphids: Small, soft-bodied insects that cluster on the undersides of leaves, sucking plant juices and causing stunted growth.

  •Black Rot: A bacterial disease causing blackened veins and yellowing leaves.

• Solutions:

  •Cabbage Worms: Inspect plants regularly and handpick worms. Use floating row covers to protect young plants, and apply Bacillus thuringiensis (Bt) if infestations are severe.

  •Aphids: Use insecticidal soap or neem oil to control aphid populations. Encourage beneficial insects, such as ladybugs, which prey on aphids.

  •Black Rot: Ensure proper spacing for good air circulation and avoid overhead watering. Remove and destroy affected plants to prevent the spread of the disease. Practice crop rotation and plant disease-resistant varieties when possible.
