How to Grow & Harvest Kohlrabi (source)

Kohlrabi has been said to have a cabbage or turnip taste, but is milder and more sweet.  It grows above ground, similar to that of a turnip.  The bulbs can be white, green or purple depending on variety.

When & How to Plant

Grow Kohlrabi in loose, average soil.  Direct-sow your seeds 4 to 6 weeks before the last frost in your growing zone; about ¼ inch deep, and 10 seeds per foot. You can start your seedlings indoors 6 to 8 weeks before the last frost as well. Transplant your seedlings when they are about 4 inches tall. Thin to 5 inches apart in rows of 1 foot apart. 

When to Harvest

Try harvesting the young leaves for stir-fry.  Harvest full bulbs when they are about 2 inches in diameter.  When cooking, use the stem as you would turnips. Store your Kohlrabi  for several weeks in the refrigerator, or several months in a cool root cellar.
