transplanted tree

I had to have a mesquite tree moved from front yard to back. It has been approximately 2 mths. The tree looks pretty bad. Small limbs break easily, Larger ones still flexible. No new growth at all. Is it still in shock or dead. How can I find out if its completely dead? I really think its a hardy tree and was very healthy before moving it. I live in southwest desert. This week temps dropped for the first time under 70.
Its been so windy 30/40 mph the last few days. my rose bushes took a beating. Should the longer vines that are leafless now be trimmed or wait till they go dormant? Same question for Jasmine bush. When to trim back? Thank you Donna
