This post would be better with a picture but we did about a 60 foot long hill and planted 50+ sweet potato plants. They were hanging tough for several weeks producing more and more foliage. This was, by the way, the only thing we planted that wasn't fenced in inside the main garden. Well,about a week ago my mom picked a leaf and started eating it. To that I said, "What the heck are you doing?" She said, "They're sweet". And I immediately thought, this could be bad. Sure enough it looks like you took a lawn mower over them and all they left were their tracks in the dirt. Unless it is just a coincidence I'm saying it was the deer. There are a few leaves left here and there so my brother and I are going to try to fence it in today and see if any pull out of it.
