I don't have a terrible deer problem, but Vicks Vapo Rub works for me. Just put it on a few young scapes, stake in the ground near your plants, backside of name tags, near by fence or post. It's greasy texture last for quite a while, depending on how much rain fall you get. I usually start early in the season, to teach the deer and other critters to go else where.
Any thing that will let the vapo rub soak in helps it last longer. Good luck.
