Orange Julius Recipe. The Orange Julius drink started out being my favorite when I went to the Mall as a teenager in the 1970's, so it has endured the test of time. Everyone had to get one. But they kept the recipe a secret for a long time. Be sure to read the History note at the bottom of the page. It's an easy recipe, the original smoothie.
Since kohlrabi is a cool-weather crop, most gardeners plant it in late winter or early spring and again in the late summer or early fall in order to get two crops a year.
In order for the plant to become well established, leafstalks should NOT be harvested the first year and only a few the second year. From the third year on, rhubarb is harvested in late May and throughout June in Ohio.
