Likely causes
Inconsistent watering
Most likelyHow to tell: Leaves turn yellow or dry before falling off during dry spells. The soil feels bone dry several inches down.
What to do: Water deeply every 14 to 30 days to soak the root zone. Ensure the water reaches at least 2 feet deep to support the taproot.
Seasonal adjustment
PossibleHow to tell: Leaves drop uniformly as temperatures cool in late autumn. This is a natural cycle for the tree.
What to do: Do nothing, as this is a normal part of the tree preparing for dormancy. Simply clear away the fallen leaves to keep the area tidy.
