References should also be sought. I think your current arborist may have taken you on a bit of a wild goose chase if the thin canopy provoked these treatments he performed. I consulted for the trim because it had not been trimmed since we moved here over 5 years ago. Every year it drops branches, nothing to make a fuss over. This tree hangs over the street and alot of people park there, mailman, delivery drivers etc. for lunch or whatever. We were a little worried about liabilty issues if a larger branch happened to fall while someone was there. So basically we just wanted to "clean" it up some. Was tree dormant when he began? Did he observe root cutting or the aftermath or were they already covered up? Yes the tree was dormant. He came after the landscaper had done the damage and he wasn't aware of the root cutting. I didn't find out about the root cutting until a few weeks ago.
I was briefly looking over the growth regulator stuff. It seems like if not done right it could cause more problems. I think that with all of your opinions I may be armed with enough questions to start calling arborists. Like I said before I'm just afraid to let anyone touch the tree now. Its hard to know who to trust.
One more thing, I was reading up on V. Wilt and these are alot of the symptoms I have described. Do any of you think that this disease is what is causing this? This is the site I was at....
