Yellow leaves on a tree can be caused by nutrient deficiencies, alkaline soil, irrigation problems, root stress, insects, disease, or normal seasonal changes. In Utah, one particularly common problem is chlorosis caused by nutrients such as iron or manganese becoming difficult for trees to absorb in our alkaline soils.

Fall is also an important time to identify structural problems before Utah's winter weather arrives. Heavy snow can place substantial additional weight on branches, particularly trees with weak unions, overextended limbs, poor structure, or previous damage.
