Thanks to everyone for your helpful advice! I wish we could get a dog to handle the bunnies, but I think a toddler, a garden, and a husband are enough for me to take care of this summer! I went with a chicken wire fence and marigolds to plant along the fence. I even found a couple plants called "Bunnies Be Gone " at Menard's, so I thought I'd plant one on each end of the fence. Maybe that will discourage them from making the jump over the stone walls on the side? Who knows. All I do know is I have invested enough time and money now that I am committed to making it work this summer!
