Question: Is there anything that will discourage rabbits in the garden?

Answer: Fencing will be your best bet. Use chicken wire to keep them out. Make sure there are no gaps, and, if the garden is large, be sure the rabbits are out of the garden when the fence goes up. One friend discovered that he had actually fenced the rabbit inside his large garden plot! You might also use the low-voltage electric shock fencing, or you might be able to capture the rabbit with a humane trap.
