Sounds shitty, Chris.
I wonder about prescribing a watering regimen, and use of a water timer, which must still be checked to see that its working.
I got the biggest single job for me to date. Nothing too crazy, 46 trees, some just simple canopy raises on western red cedars along hard gravel (renting a 60' self-propelled 4wd Genie lift, one of the few times a year where a bucket is really a big timesaver), and many easy, smaller removals with access, or drop and leave. I'll have two 28'' DBH cedar sticks to crane over the garage from about 50' with a 22 ton, and a 40" cedar stick that leans somewhat, but somewhat closer radius, I think.
I'm going up there in a little bit, I'm going to transplant a few 2" vine maples to my house, rather than just cutting them down. Knock down a few easy trees, too, maybe. Having another look will help me make a more exact work plan, and its only 5 miles down the county road from me.
