Hello Dalesman, this sounds really frustrating, presumably rodents, and they are difficult to protect against. I lost a lot of oca to (I think) field mice last November, the problem being that you cannot harvest ova until after mid November.
Sweet potatoes being late to crop means the same problem and rodents do love them. I have a couple of sweet potato plants in a bed outside at the moment, wonder what may happen. Perhaps we should stick to growing potatoes!
