Any advice on how to keep chipmunks away? I'm using 3' chicken wire around a potted veggie plant right now, and it does work! But next year, I'll be planting straight into the garden again, and those pests sure are a chore. I'm thinking about using chicken wire again, and maybe running more chicken wire as a sort of frame flat on the ground under the fence? Not sure how to attempt it this time. Thanks~
