There are many problems that you can encounter when growing your own backyard garden. Lack of rainfall, unfavorable temperatures and plant diseases can all play a part in a garden's demise. Rabbits can destroy a garden overnight by eating all your tender vegetables. Fences are a good deterrent to keeping them out, but you must install them properly to prevent rabbits from digging under them.
Dig a trench around your existing garden fence about 6 inches deep. Set the dirt aside to fill back in later.
Measure the perimeter of the fence (all four sides) and cut a piece of 1-inch mesh galvanized fencing the length of the perimeter. Use tin snips to cut the fencing.
Cut the piece of fencing so that it is 2 feet tall. If your perimeter is 16 feet, you will now have a piece of fencing that is 16 feet by 2 feet.
Wrap the galvanized fencing around the outside of the other fence so that it's all the way to the bottom of the fence. Tie it to the other fence with 14 gauge galvanized wire.
Fill the trench back in with dirt. You should now have a rabbit proof garden because rabbits will run into the mesh fence if they try to dig under the above-ground fence.
