Crab apple tree
We are in Edmonton Alberta in October. We expect the leaves of our trees to turn color and fall off. The leaves on the crab apple are drying up, and they seem to be getting darker but not really changing color. What is going on? We had a very wet summer this year.

Can you please send me a weil lit picture of the whole tree and of an affected leaf and a close up of the front and back of a leaf. Thank you.
