Reflective tape, fluttering objects, and other scare devices may help temporarily. Succulent leaves, shoots, and flowers are all delicacies to rabbits. If you have young plants that are being chewed to the ground, suspect rabbits. Rabbits also may chew the bark of fruit trees. Rabbit damage may be distinguished from deer damage by the teeth marks on the branch or twig.
Deer lack upper incisors and they leave a ragged edge on the branch.
Excluding rabbits from the garden is the best way to deal with them. Bury the fence 1 foot in the ground, leaving 2 feet above ground. Individual plants and trees can be protected with wire mesh cylinders. Repellents may provide some short-term control. Trapping is possible, but check with local wildlife authorities first.
