First of all thank you guys so much for the replies. I am not very good at this stuff so I'm going to have to research the suggestions Treelore made (Because it sounded like greek to me...lol) but in response TreeDimensional i am going to try to fill in some of the blanks the best I can. I also got on the roof to try to get you guys some better pictures.
Chemicals - The Arborist said we needed to spray for "Verticillium Wilt" I dont know what he sprayed and I'm afraid to call him because he will then ask why and want to come out again and fix it. I paid him $500 for the so called structural trim and another $150 for the spray I'm afraid to let anyone touch it now. I have lost all trust in people here, seems no one REALLY knows what they are doing. But if you need to know I will certianly call.
Here is a pic of what he called "Verticillium Wilt"
I sprayed Ace Hardware brand Malathion. I mixed it according to the directions and sprayed it all over the bottom 2/3's of the tree (as far as the hose would shoot). It was a liquid that I mixed and poured in a sprayer similar to the miracle grow plant food sprayer.
Here is a picture of the critters I know they are small but you guys seem to be good
Ok now the root loss. The whole back yard was tore up. I really have no idea exactly where the roots were cut but I will show a pic or 2 of the yard so you can see where the grass is and obviously where the sprinkler pipes should be. The roots on this tree or incredibly thick as you can see wee couldnt plant much of anything near the trunk.
The yard -
The trim was done about 3 months ago. He didnt take out much. He said I never wanted to cut off the top. I wish I knew more about this question. I do know that he didn't "seal" the cuts (are you supposed to?) He didnt cut any of the huge branches just some of the mediumish ones that seemed to weighing down the larger branches (wow I hope that makes sense)
I will try to answer anything else as best I can. Like I said I will call him if you think it will help. Just let me know.
Once again thank you so much for your help. And if anyone knows of a trustworthy arborist in Redding, Ca I would love to hear about them!
