I would suspect that your heat/drought conditions and appropriate deep watering should be your first consideration.


Desert willow trees are know to be relatively resistant to pests and diseases, but there are some possibilities for disorders:


Verticillium wilt

Environmental disorders:
Mineral deficiencies
Nutrient and mineral excesses
Poor water management

Vertebrates: gophers

It is not possible for us to give a definitive diagnosis without more information on growing conditons and management. You may need a site visit from a local consulting arborist or university extension service advisor.
