A wire fence is the best defense but if you cannot fence the property try using red pepper. I sprinkled red cayenne pepper onto the new growth of tulips and other tender foliage and this keeps the bunnies at bay in my garden. You can also buy sprays that use pepper or herbs in a liquid form to make your garden too hot to handle. A company called Messina Wildlife makes an organic, pleasant smelling repellent that uses rosemary oil, mint oil and cinnamon oil in a spray they call \"Rabbit Stopper.\" Hop to it, and Keep growing, Marianne Binetti
