I have 2 Ash trees in my front yard that do not look very healthy. They both have sparse leaf coverage , some dead branches and a bluish fungus on the dead wood. What can I do to save my trees? Thanks for your help.

Up here in Northern Illinois, we have a new invader, called the Emerald Ash Borer, that is killing our Ashes. Hopefully you don't!
