Answer: It may be that the trees are beginning to compete with each other for water and nutrients and the weakest growers are losing out. It may be that encircling roots not untwined at planting are beginning to take their toll on the trees, if the roots are still in a circle underground. It may be that there is a disease problem or pest problem that you have not noticed. You might want to consult with your county extension (285-4620) as to what is happening, just in case it is something that could spread and could be prevented.
