LOL! It's Chelle that has rutabagas!!! Another root veggie. Kind of bland. A lot of people cook and mash with potatoes.
I have only ever sliced and salted kohlrabi and eaten raw. Not sure if there are other ways to prepare. But you haven't said you are growing radishes. They're easy. Did you do some and I missed? Well, sometimes they miss and go to seed before forming.they don't like the heat either but they are ready in about 30 days.
