Sorry for posting this in this forum. But I thought I am more likely to get an answer here from our friendly, knowledgable members than from other places. I moved in a new house this summer. Now I notices several trees are sick. This is a cherry blum (?) in the front yard, it looks seriously sick comparing to the same type tree in the back. It's leaf, root area and a crosscut of a dead branch were shown. What do I need to do to save it?

Do I need to something before it becomes too late? View attachment 258588 View attachment 258589 View attachment 258590 View attachment 258591 Any help greatly appreciated.
