I have evergreen trees in my garden. They all seem to have brown leaves within the crown, are they diseased or dying?

Due to the density of most coniferous trees, it is quite normal for internal branches and leaves to die back. This is due to the lack of light penetrating through the dense crown of the tree. Although if brown leaves begin to appear on the outside and tips of the branches there may be a problem. If this is the case we will be able to inspect the tree and provide you with the best advice as to the trees health.
