This is going to sound weird, but I swear it's true. Did you know that collard green stumps that are planted in the ground will take root and produce more leaves? By the stump I mean the main core/stalk that all the leaves grow off of. I figured this out when I went out to my compost pile and noticed that the stump or main stem of a collard plant had started to root itself. I carefully dug it out and transplanted it into the garden. It didn't get bushy like a collard from seed might, but darned if it didn't regenerate enough leaves for me for a few suppers. It even produced flowers and seeds at the end of the season, and this spring I have hundreds of baby collard greens scattered through the garden and even into my lawn.
Now I'm wondering if lettuce and cabbage stumps will do the same thing. Will let you know how it turns out. Has anyone tried this before?
