Although I don't live in Colorado, I do live here in Arizona. We have a Fan Texas Ash tree (2). Is it o.k. to trim the trees in the summer here in central Arizona (Phoenix)?
Both trees are fully mature and healthy, it's just that the monsoon season is upon us and I'm concerned that the trees may not sustain the high winds associated with the monsoons. The trees have never been thinned out inside the basic tree structure.

Best advice I can give is to contact your local Extension office.
