Suzan,  Here a link to some pictures and a post I made back in June.  The tree looked bad before I inarched some other rootsstocks to it.  Now it looks better than ever, and had a bumper crop this season.  Like Joe menitoned, I believe having the different rootstocks, providing the tree with nutrients, has resulted in a healthier tree.  I think I have three different rootstocks grafted to it.
