Many Utah homes have fruit trees planted as a part of the home landscape.  Fruit trees provide shade, screening and beauty, as well as providing fruit for table use or preservation.  However, as trees get older, they get taller, and most of the fruit production moves to the tops of the trees where there is light.  Fruit in the tops of the trees are also difficult to spray and harvest.
