Hi, This is my first post and hope someone will give me some advice. We went to a nursery and bought a 12-15 foot autume blaze maple tree. It is a beautiful tree. The nursery planted it in April It looked liked it was doing pretty well until about 3 weeks ago. Now the leaves are all turning color. It looks like I would imagine it looking in the fall. I called the nursery and they told me it was a common problem. They said it was probably under stress. I was told to water it slowly, about 20 minutes a day, every day for about a week. I live in lower Michigan and the weather has been very warm the past few days. Does this seem to be the right thing to do. I told the nursery that they planted the tree in clay and they said that wasn't a problem. They said the leaves would probably fall off early, maybe in September, but not to worry. Thanks so much for any imput.
