sugar maple trees dying - HELP!
We've been living at our place for 28 years. I've planted different sugar maples at different times, some dug up from my fathers woods, some planted by tree spade by garden centers. They are planted in different spots on my property. I have lost FOUR of them so far. They are mature trees that were very healthy for many years. They start out with some limbs dying, then more, and finally the whole tree goes. I sure don't want to lose anymore. Is there anything I can do about this? I am near Milwaukee and there are tons of sugar maples everywhere so I know they do well in this climate.
I have some beautiful mature silver maples but so far they don't seem affected.
