My cukes are planted along the chain link fence next to the driveway. There is an 18” wide flower bed between the fence and the driveway. It can support 2 dozen cuke vines and is right outside the kitchen. It makes an ugly fenceline useful.
My favorite way to cook kohlrabi is to dice into 1/2 inch cubes, steam them until tender, and serve in a white cream sauce.
Another way I use them is in ham-hock and bean soup, I dice the kohlrabi into 3/8" dice and throw them into the pot in the last hour or so. Ham and kohlrobi go well together.
