|Kohlrabi (Brassica oleracea)|
Plant in full sun about 3 inches apart and 1/2 inch deep. Keep them consistently moist for the best flavor. A layer of mulch is helpful to retain moisture during dry weather. Like other members of it's family, kohlrabi is plagued by insects like cabbage butterflies. As it doesn't need pollination, it benefits from a row cover to keep insects away. Harvest when the bulb is about 2 inches in diameter. Larger tubers tend to be woody/fibrous so successive plantings and frequent harvests are beneficial.
Happy Gardening! :)
