The problem with your tree starts with the grade change around the base of

changed the grade beyond the well, it would have had a chance.  If that tree
was there before the wall and fill, then I would say it is troubles in the
rhizosphere especially suffocation of the tree by reduction of free oxygen
at rhizoplane.  Trees require oxygen for respiration.  Filling in around a
tree like that greatly reduces free oxygen in rhizoplane.  In that case it
may just be too late for the tree and trying to fix that very easily could
make things even worse.  Trees do breath.

When was the grade changed?

My tree is dropping tons and tons of leaves. We've had a very wet
Spring and Summer here in NW Arkansas. Here is a link to some close-
ups of the leaves. The yellow detached leaves fell from the tree
today. The green leaves were pulled from the tree. I'm trying to
determine if I can treat the tree and make it stop dropping leaves. In
prior years it has dropped some leaves due to scorching I presume but
nothing close to this year. I appreciate your help.

John,
Thanks for your reply. I bought the house three years after the tree
was planted (it has been there a total of 8 years) and the lttle wall
was already there when we moved in. They did create a circle around
the tree so that the the trunk didn't get covered at all. Picture a
shallow funnel about 8 feet across with the tree in the middle. Did
you see the pictures of the leaves? I thought it might look like a
fungus - we did get a tremendous amount of rain in the Spring and
early Summer. I do have mulch right up to the trunk. thanks again
for your help.
