Aleppo Pine Blight in Phoenix is starting to occur more often in the desert southwest. Pine Blight is the needles that are starting to die and in some cases killing the large mature pine trees. If you look online you will see lots of different solutions and causes. However, one of the best studies of this was done by the University of Reno Nevada Cooperative Extension.

There are different solutions offered by several tree companies and tree arborists. We like the solution offered by Treeàge USA, in this video they created about the Aleppo Pine Blight:
