    The Causes of a Palo Verde Tree's Leaves Turning Brown. Sonoran Desert plant adaptations aid plants in surviving the desert’s hot environment -- trees with green trunks that carry on photosynthesis in the absence of leaves excel in this Arizona desert. Trees are rare in the harsh desert habitat and those few that have evolved to thrive in summers when temperatures routinely reach 115 degrees Fahrenheit are treasured by most homeowners. It’s hard to not respect a tree that shades the desert floor as well as home landscapes while nursing young cacti. Being concerned about potential health issues of these desert-dwelling plants is not unusual and being anxious when the leaves of the palo verde turn brown is natural.
