I have posted this on the Maple forum also since these pests and I are somewhat species specific but I am having more problems this year with rabbits making a meal on my young grafted Japanese Maples than I have ever had before. They occasionally hit a Ginkgo or two also. I have a few brush piles that I need to burn and I feel that this would help a great deal. I have been putting mothballs around my blocks of trees and plan on putting human hair in the vicinity of these plants. Other options that I am considering are spraying a dog and/or cat repellent, old pepper sauce, and an air freshener called "Money House Blessing Gold Offering Spray". This freshener may be a tool of practitioners of Voodoo, it looks like some of that New Orleans type stuff. I put too much work into my trees to have this go on much more. Maybe a granulated carpet freshener will work in warding off these terrible rodents. Any suggestions from others will be appreciated.
