Provide a well- drained soil with a good supply of organic matter. Kohlrabi seed started inside takes 4 to 6 weeks to produce a suitable transplant. Outdoor planting times are March 20 to April 20 or late June. 18 to 24 inches apart. Rapidly grown plants give the best quality.
Deep cultivation can stunt plants and slow down growth causing fibrous stems.
Harvest the stems when 2 to 3 inches across. This information is for educational purposes only.
