How Much Space Does Kohlrabi Plants Need?

Space kohlrabi 9 to 12 inches apart in an area with plenty of sun and rich, well-drained soil with a pH of 6.5 to 6.8.

What Type Soil Does Kohlrabi Like

Kohlrabi that matures in cool weather is deliciously sweet. Kohlrabi needs at least 6 hours of full sun each day; more is better. Give it fertile, well-drained, moist soil with plenty of rich organic matter. A soil pH between 6.5 and 6.8 discourages clubroot disease.

Planting Instructions

Plant in a location that receives ample sunlight (at least 6 hours, more is better) and has rich, slightly acidic, well-draining soil. While kohlrabi isn’t a heavy feeder, it is helped by having its soil dressed with 1 inch of compost before planting.

Avoid planting kohlrabi where other vegetables in the Brassica family have been grown in the previous 2 or 3 years. This helps to prevent the spread of disease and nutrient deficiencies. In spring, once soil temperatures have reached at least 45°F (7°C), sow seeds directly in the garden, for an early to mid-summer harvest. Sow seeds 1/4 to 1/2 inch deep. In rows, space kohlrabi seeds about 2 inches apart in rows 10 to 12 inches apart.
