Kohlrabi seeds grow into compact, upright plants characterized by a rounded, swollen stem that develops above the soil surface. Kohlrabi is a cool season crop that performs well in mild to temperate climates and is commonly grown during spring and fall. The plants adapt well to garden beds, raised beds, and container growing when provided with fertile, well drained soil and consistent moisture. Its uniform growth habit makes it suitable for short season cultivation in a wide range of regions.
