Fence

• A 6- to 8-foot tall fence can keep deer off an individual's property and away from peach trees. However, there are some difficulties with building and maintaining such a fence, especially in residential areas. In cases where a fence is not practical, building a small barrier around the base of each individual tree can prevent deer from being able to reach the fruit. Fences are a simple but expensive way to keep deer out.
  
  

Deer Repellent Plants

• There are certain plants that deer dislike. Planting certain things around the edge of a property and around the peach trees can help to dissuade deer from coming onto the property, although this method works best when combined with other forms of repellent. Some of the plants that work as natural deer repellents include things like fir and pine trees, larkspurs, crocuses, rosemary and thyme, according to the Washington Department of Fish and Wildlife.
  
  

Inexpensive Repellents

• Homemade deer repellents work for keeping deer away from peach trees. They are less effective than store-bought deer repellent, but using several cheap methods of keeping deer away helps to keep the deer from becoming accustomed to the repellent. One method is to cut bars of deodorant soap into pieces and hang them from the branches of the peach trees. Another method is to collect mesh bags of dirty human hair, according to the University of Minnesota.
  
  

Store Bought Repellents

• Store bought repellents are more effective in keeping deer away from peach trees. Many of these involve sprays that are put onto the peach tree itself, which make the fruit taste bad to the deer. Some store bought repellents are placed around the trees and their unpleasant smell is designed to keep deer away. According to the University of Minnesota, studies show that these repellents are not totally effective. Combining repellents can be more effective.
  
  

Considerations

• Deer are a common problem for many gardeners and farmers. Peach trees' leaves, branches, bark and fruit are all vulnerable to deer that are looking for an easy meal. Keeping deer away from a peach tree is a chore for many people; deer can become accustomed to certain repellents, and the effectiveness of repellents wears down over time. Reapply repellents as often as necessary to keep deer away from a peach tree.
