Are there trees that are deer resistent?
Deer are persistent when they have found a food source that is appealing to them. Many commercial repellents and structural obstacles (i.e. 8 high fences) can be bought to help protect your landscaping from deer, but things such as repellents only work to a point, as long as you can re-apply them periodically. Like many animals, deer can sense when a plant is poisonous and will generally avoid eating such a plant. They also will go out of their way to avoid spicy foods and plants that give off foul odors.
