Kohlrabi, a member of the cabbage family, is a versatile vegetable that adds a unique flavor and texture to salads, stir-fries, and soups. Growing kohlrabi from seed is an easy and rewarding task that can yield a bountiful harvest. In this comprehensive guide, we will delve into the steps and techniques involved in successfully planting kohlrabi from seed.
Choosing the Right Variety
The first step in planting kohlrabi is selecting the right variety. There are many varieties available, each with its own unique characteristics. The Purple Vienna variety is known for its deep purple skin and sweet flavor, while the White Vienna variety has a milder flavor and a pale green skin.
Preparing the Soil
Kohlrabi prefers well-drained soil that is rich in organic matter. Amend the soil with compost or manure to improve drainage and fertility. The ideal pH range for kohlrabi is between 5.5 and 6.5.
Starting Seeds Indoors
Kohlrabi seeds can be started indoors 4-6 weeks before the last frost date. Fill seed trays with a sterile seed-starting mix and sow the seeds 1/4 inch deep. Keep the soil moist and provide plenty of light.
Transplanting Seedlings
When the seedlings have developed their first set of true leaves, they are ready to be transplanted outdoors. Harden off the seedlings by gradually exposing them to outdoor conditions for a week before transplanting. Dig holes that are 12 inches apart and plant the seedlings at the same depth they were growing in the seed tray.
Watering and Fertilizing
Kohlrabi requires regular watering, especially during hot, dry weather. Water the plants deeply at the base, avoiding getting water on the leaves. Fertilize the plants every few weeks with a balanced fertilizer.
Mulching
Mulching around the kohlrabi plants helps to conserve moisture, suppress weeds, and regulate soil temperature. Use organic mulch such as straw, hay, or shredded leaves.
Pests and Diseases
Kohlrabi is susceptible to a few pests and diseases, including cabbage worms, aphids, and clubroot. Monitor the plants regularly for signs of pests or diseases and treat them accordingly.
Harvesting
Kohlrabi is ready to harvest when the bulbs reach 2-3 inches in diameter. Use a sharp knife to cut the bulbs from the stems. Kohlrabi can be stored in the refrigerator for up to 2 weeks.
How to Plant Kohlrabi from Seed in Containers
Kohlrabi can also be grown in containers. Use a container that is at least 12 inches wide and 12 inches deep. Fill the container with a well-drained potting mix and sow the seeds 1/4 inch deep. Water the seeds and keep the soil moist. When the seedlings have developed their first set of true leaves, thin them to 12 inches apart. Water and fertilize the plants as needed.
Companion Planting
Kohlrabi can be planted with a variety of companion plants, including carrots, celery, onions, and tomatoes. These plants can help to deter pests and improve the overall health of the kohlrabi.
Troubleshooting
Problem: Leaves turning yellow
Solution: This could be a sign of nitrogen deficiency. Fertilize the plants with a nitrogen-rich fertilizer.
Problem: Holes in the leaves
Solution: This could be caused by cabbage worms. Use insecticidal soap or Bacillus thuringiensis (Bt) to control the worms.
Problem: Stunted growth
Solution: This could be caused by clubroot. Remove the infected plants and do not plant kohlrabi in the same location for several years.
