Leaf spot disease
PossibleHow to tell: Leaves develop dark spots and turn yellow before falling off early. This is most common during wet, humid seasons.
What to do: Rake up and dispose of all fallen leaves to prevent the fungus from spreading. Improve air circulation around the tree by thinning out crowded branches.
Severe drought
PossibleHow to tell: The tree drops leaves to reduce water loss during an extended dry period. The leaves may turn yellow or brown before they fall.
What to do: Increase your watering frequency to ensure the soil stays consistently moist. Apply a thick layer of mulch to help the ground hold onto water.

When to worry
Worry if the tree loses a large portion of its leaves in mid summer. Some leaf drop is normal as the tree prepares for autumn, but it should not happen early in the season.
Stopping it coming back
Keep the area around the base of the tree clean of debris and maintain a consistent watering schedule throughout the summer.
