Holes in the leaves of my weeping cherry?

Question:i recently planted a 5ft. weeping cherry tree in my garden. The soil is quite moist. I've noticed lots of tiny holes in the leaves of my tree, but no bugs to be found. And right before it becomes a hole, it looks like there is a small brown/yellow spot, which falls out...and makes the hole. What is that and what do I do?

Answers:
Take one of the infected leaves to a certified gardening store or shop, and ask them. They should be able to tell you, if those trees are grown locally by more people than you.
