There are many, many possible reasons this could be happening. I would examine the tree/leaves thoroughly for signs of insects. Lace bugs, for example, can cause yellowing leaves and defoliation. Leaves that are overall yellow could signal a nitrogen deficiency while yellow leaves with green veins could signal an iron deficiency. Yellow leaves can also be a sign of under-watering or over-watering. More information on these and other possible scenarios are described in detail in the following articles:
