This Palo Verde tree fell when a dust storm hit Waddell. One of the factors in its early demise was the way in which it was watered. Drip emitters were located near the trunk which created a moist environment that was hospitable to harmful fungi and other microorganisms. The Fungus used the root system as a food source which reduced its structual integrity. In turn this weakened tree was not able to resist the force of the storm. Palo Verde trees need to be watered very little, if at all. They are well adapted to our desert climate.
