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.
Once you have the kohlrabi at the desired size, you simply pull the entire plant up. I usually let all the kohlrabi get about the same size, but some will be a bit larger while some are smaller. It really depends on how many plants you are growing, and how you intend to use them.
