Hello, my peach tree has developed two black areas on its branches. It looks to be breaking the branch apart. How can I tell if this is a virus or cankers. And what would the treatment include. Also, the trunk of the tree is starting to blacken as well. 

Hi!

I have 2 what appears to be fringe trees on my property. I am a new owner, the previous owner had planted these, I think they might have been in the same spot for 3ish years.

Last year I observed that one of the trees (Tree 2 image below) didn't get any leaves at all. The other (Tree 1 in my images) had leaves but on only half of the branches. It had beautiful flowers, but again only on half the branches and they looked a but sparse.

I am worried they are dead/dying. Can I do anything to save the one which is not fully dead? I am in New Jersey.
