The red cabbage is a kind of cabbage, also known as Blaukraut after preparation. Its leaves are colored dark red/purple. However, the plant changes its color according to the pH value of the soil, due to a pigment belonging to anthocyanins..

• Red cabbage seeds
• Seed trays or pots
• Seed-starting mix
• Garden soil or potting mix
• Garden tools (shovel, trowel)
• Fertilizer (preferably balanced, organic)

1. Start Seeds Indoors: Red cabbage seeds can be started indoors about 6-8 weeks before the last expected frost date in the spring. Here’s how to do it:

• Fill seed trays or pots with seed-starting mix.
• Plant the seeds about 1/4 inch deep and 2-3 inches apart.
• Keep the soil consistently moist but not waterlogged.
• Place the trays or pots in a warm and sunny location or under grow lights.
• Seedlings should emerge in 5-10 days.

2. Transplant Seedlings: When the seedlings have grown to be about 4-6 inches tall and have a couple of sets of true leaves (usually after 5-6 weeks), they are           ready to be transplanted outdoors. Choose a location with well-draining soil and full sun.

3. Prepare the Soil:

• Red cabbage prefers well-draining, fertile soil with a pH level between 6.0 and 7.5.
• Incorporate organic matter into the soil, such as compost, to improve its fertility.

4. Plant Seedlings:

• Space your seedlings about 12-24 inches apart in rows, depending on the variety and your available space.
• Plant them at the same depth they were growing indoors, making sure to cover the roots completely.

5. Watering and Care:

• Keep the soil consistently moist, but avoid overwatering, which can lead to root rot.
• Mulch around the plants to help retain moisture and suppress weeds.
• Fertilize the plants with a balanced fertilizer every 3-4 weeks.

6. Pest and Disease Control:

• Keep an eye out for common cabbage pests like cabbage worms and aphids, and take appropriate measures to control them.
• Practice crop rotation to minimize disease issues.

7. Harvesting:

• Red cabbage typically takes around 80-100 days from transplanting to maturity. Check the specific variety’s recommended maturity date.
• Harvest when the heads are firm and reach their full size. Cut the head off at the base with a sharp knife.

8. Storage: – Store harvested red cabbages in a cool, humid place like a root cellar or refrigerator. They can last for several weeks to a few months.
