Kohlrabi Seeds - Green

Kohlrabi seeds grow into compact, upright plants known for their swollen stem growth above the soil surface. Green kohlrabi is suited to cool season cultivation and performs well in temperate climates with mild temperatures. Plants adapt well to garden beds, raised beds, and container growing when provided with consistent moisture and fertile, well drained soil. Kohlrabi is commonly grown as a short season crop and is valued for its uniform growth and adaptability to spring and fall planting.
