Q.Sweet Potato Vine (Sweet Caroline)
Something is eating my sweet potato vine. I thought it might be a ground hog bu I raised it up higher on crates. It is unlikely to be a deer. In July, something ate all the leaves. They grew back and seemed to be fine. When I went to bed last night, it was fine. This morning all the leaves were gone. Just stems. What to do?
I'm sorry that you are having this problem. Animal pests are a difficult problem for any gardener. Groundhogs, aka woodchucks, actually can climb like squirrels, and they eat gardens hungrily, so they are still a possibility. Rabbits, mice, and ground squirrels are also possibilities. Enclosing plants in metal mesh cages can be very helpful, even if you just enclose a few feet near the ground, at least for some animals. Here are some articles that may help:
