What may have caused my maple to change color and shed leaves so early in the summer? Leaves dropped in July after 3 yrs of normal growth. I live in Edmonton Alberta, Canada

As Moongrower hints, usual cause is drought.

Root damage, or root parasites can do the same thing for the same reasons--not enough water to the top.

This year was a very wet spring/early summer. The previous years were much drier and it grew fine. First year in 5 that we've had muchrooms growing in the yard because of rain.

Have you checked for root damage as Tubd. suggested?
