Purple Vienna - Kohlrabi Seeds

Kohlrabi develops best quality bulbs when grown in the cool weather of early spring or late fall. Plant seeds directly into the garden starting 4 weeks before average last frost date continuing until about that date. You can also start seeds indoors 4-6 weeks before transplanting. Optimum soil temperature for seed germination is 45-80 degrees. Kohlrabi is a cool season crop so avoid letting it mature in hot weather. Grow it in the spring, then again in the fall. Frost can improve the flavor. Harvest swollen bulb when small to avoid it becoming tough and woody.
