Spray-on treatments can protect trees and shrubs but often times have to be repeated after a bout of bad weather. Fences help if they are high enough, or if the area they cover is small. Deer dislike jumping into an smaller enclosed area. Hanging shiny reflective aluminum pie pans work for a while but the deer eventually become used to them. Having a dog available to guard the trees will keep the deer away, and if it is not possible to have a dog, scattering the scat of one around the plants will often fool the deer.
