You're not the only one who enjoys plump, fresh beans harvested from your backyard garden. Rabbits often prune bean plants down to the ground, eating both the plant and its bean pods, according to the University of Wisconsin. Defend your garden and your future bean harvest by using a combination of physical and chemical controls to keep rabbits from ruining your bean crop.
Deter rabbits by modifying your landscape to make it less attractive to the animals. The University of Minnesota suggests removing tall stands of grass or shrubs and piles of debris where rabbits may hide. Keep a wide, open border of 20 feet around your vegetable garden, since rabbits are wary of crossing large open spaces.
Setup a fence around your vegetable garden. This is the best protection for your garden, according to the University of Illinois. To successfully keep out rabbits, the university suggests a 3-foot fence of chicken wire. Bury the fence's bottom 6 inches, bent at a 90-degree angle, to keep the pests from digging under the fence.
Erect wire fencing around your bean plants alone if fencing your entire garden is too expensive, according to Iowa State University. Encircle each bean plant with chicken wire, keeping the wire approximately 2 inches from the plant itself. Just like with a garden-wide fence, the encircling wire should be 3 feet high.
Spray your bean plants with a rabbit deterrent spray. This is ideal only when the plants aren't producing beans, since such deterrents leave a nasty taste on any surface upon which it's applied. Use any of the many sprays available at garden stores. North Dakota State University recommends using one formulated with capsaicin, an all natural extract from peppers.
