It worked every bit as well as I knew it would, and maybe even better! In the spring, right at leaf-out, I noticed what I would call some "tentative" browsing. Since the trees are still young and I knew wouldn't be bearing fruit, I gave them a light spray. They left them right alone after that. They remain untouched, and I have personally seen deer, especially does with fawns, walk right on by the trees, and they are at a perfect browsing height for both the does and fawns. If you ever need a testimonial from a guy with a master's degree in deer damage control, I'm there for you.
