PLANTING INSTRUCTIONS

Purple cabbage, also known as red cabbage, is a striking and nutritious addition to any garden. With its vibrant color and crisp texture, it is not only a culinary delight but also a visual treat. Purple cabbage thrives in cooler temperatures and is relatively easy to grow, making it a great choice for both novice and experienced gardeners. This guide will walk you through the steps to cultivate healthy, productive purple cabbage plants.

• Best Time to Plant:

  Purple cabbage is a cool-season crop that can be grown in both spring and fall. For a spring harvest, 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 in mid to late summer, or start seeds indoors and transplant them 6-8 weeks before the first expected frost.

• Soil Type:

  Cabbage prefers well-drained, fertile soil rich in organic matter. The ideal soil pH for cabbage is between 6.5 and 6.8. Before planting, amend the soil with compost or well-rotted manure to improve fertility and soil structure. Purple cabbage also benefits from a soil that retains moisture but does not become waterlogged.

• Spacing:

  Proper spacing is essential for healthy growth and to prevent disease. Space plants 18-24 inches (45-60 cm) apart in rows that are 24-36 inches (60-90 cm) apart. If you are growing cabbage in a raised bed or smaller garden, you can reduce the spacing slightly, but ensure there is enough room for the heads to develop fully.

CARE TIPS

• Watering:

  Cabbage requires consistent moisture to grow well. Water the plants deeply once a week, providing about 1-1.5 inches (2.5-4 cm) of water. During hot and dry periods, you may need to water more frequently. Mulching around the plants helps retain soil moisture and keeps the roots cool.

• 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 throughout the growing season. Alternatively, side-dress the plants with compost or organic fertilizers to provide a steady supply of nutrients.

• 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:

  Purple cabbage is usually ready to harvest 70-100 days after planting, depending on the variety and growing conditions. Harvest the heads when they are firm and have reached the desired size, typically about 4-6 inches (10-15 cm) in diameter. The color should be a deep, vibrant purple.

• How to Harvest:

  Use a sharp knife to cut the cabbage head from the plant, leaving about 1 inch (2.5 cm) of the stem attached. After harvesting the main head, the plant may produce smaller side heads, which can also be harvested. Regularly check the plants and harvest when the heads are firm to prevent them from splitting.

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: 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.
