The edible part of kohlrabi is a large bulb grown on a stem just above the ground. When the bulb is young, no more than 2 1/2 inches across, the flesh has a sweet, mild turnip-like flavor. It is a delicious vegetable, highly prized by many who appreciate the sweet, fine grained flesh.
A member of the cabbage family. Prefers cool weather. Does best in a rich, well-drained loam. For an early crop, sow seed 1 inch apart, 1/2 inch deep, as soon as the soil can be worked. Cultivate the same as cabbage. Sow again in mid-summer for a fall crop, in rows about 18 inches apart. Later thin plants to 5 inches apart in rows. Harvest when the bottom of the bulb reaches 2 to 3 inches in diameter. Prepare for the table in the same way as turnips. Allow 2 weeks for germination. A packet sows 40 feet of row; one ounce sows about 300 feet.
