Some animal has been digging at the ground around my pepper plants. The rest of my garden is fine, including my tomatoes. This is a regularly occurring problem, every two days or so.
What animal could be responsible for this? I've seen a skunk, squirrels, chipmunks, rabbits, birds, toads and a cat all roaming around my yard, so I'm not sure what I'm trying to defend against.
Are there any suggestions for keeping them protected?
