About a month ago I put the top of one in a bowl of water on the kitchen sill. The growth is crazy. Cut slips off the growth and put them in a vase they’ve all rooted. I know it’s too early and it was done more as an experiment on my part. They just might make it to spring and the green in the window sill is nice. They do go through the water.Does anyone know how to start new sweet potato plants? They are cheap now so i thought i might store some in the root cellar for spring.
