Rabbit proof cages and fences are a practical and inexpensive means of protecting smaller areas or valuable plants. Individual woody shrubs and young trees can be protected by placing a wire guard or cage of woven wire netting around them. Plastic animal netting can also be effective, but it has to be securely fastened to prevent a persistent rabbit from getting through. Two inch poultry wire works, but the barrier must be placed several inches from the plant. Rabbits can also be excluded from an area by constructing a rabbit-proof fence. Rabbits are not good climbers, do not ordinarily jump fences, and except for domestic rabbits are not good burrowers. A fence of at least 1″ mesh wire, 18-24″ high around whole gardens, flower beds or other places will provide needed protection. The bottom of the fence can be buried in the ground at least 6″ to prevent rabbits from digging under the fence. Tree wraps will also help prevent gnawing of small trees, but make sure that you wrap the trees high enough that rabbits can't reach above the wrap, especially when standing on deep snow.
