CULTURE: Kohlrabi prefers mild or cool weather. It is grown throughout the season in the North, and during fall and winter in the South. Sow 15 seeds/ft., 1/4- 1/2" deep, in rows 12-18" apart. Thin fresh market varieties to 4" between plants. Thin storage varieties such as 'Kossak' to 10" between plants. For earliest crops start in flats or plug trays and transplant.
