Getting Started with Kohlrabi Plants
Kohlrabi is a member of the cabbage family and has many of the same growing needs. A cool-season vegetable, it can be grown in the spring or fall garden.
How to Plant Kohlrabi Seeds?
Sow kohlrabi seed 1/4 to 1/2 inch deep and 4-6 inches apart. Space rows 18-36 inches apart. Kohlrabi grows best in full sun and in well-drained soil.
When to Plant Kohlrabi?
Kohlrabi can be planted in the spring when soil temperatures reach at least 45 degrees. To extend the harvest, sow seeds every two weeks. Kohlrabi can also be planted in late summer to early fall. Kohlrabi grows best when the air temperature is 65-75 degrees.
When to Plant Indoors?
Kohlrabi can also be started indoors 4-6 weeks before transplanting to the garden. Because seeds will germinate at lower temperatures, no heat mat is needed when starting kohlrabi seeds indoors. Keep the temperatures cool, between 60 and 70 degrees.
How Long Do Kohlrabi Seeds Take to Germinate?
Kohlrabi seeds typically germinate 3-10 days after sowing.
When and How to Harvest Kohlrabi?
Most kohlrabi varieties have the best flavor and texture when harvested at 2-3 inches in width. In the fall, when temperatures are cooler, kohlrabi can grow a bit larger without losing its quality. To harvest kohlrabi, use a sharp knife to cut the root from the bulb.
How Long Does Kohlrabi Keep After Harvesting?
Kohlrabi can be stored in the refrigerator for about two weeks after harvest.
