Couple of years ago a client in need of more advice on her bedraggled Cottonwood was referred to me.
Cottonwoods carry a bit of a professional and social stigma around here. So saving this one felt special.
Her Cottonwood got the works: deadwooding, structural pruning, and target limb reductions; two competing Elms were removed from the Cottonwood's CRZ; TGR and deep root fertilization to round it out. On May 16th 2025, after the pruning work was completed, the tree took a direct hit from an EF3 tornado. This was the first time (for my buddies and I) that a tree under our counsel and work had been tested by a tornado. Wow! The tree performed like a champ. There were small branch failures, but no major tree part failures. If you go to that neighborhood today, you can clearly see the swath that was cut through the urban forest - her tree stands smack dab in the middle.
I last visited the tree in the fall of 25'. Deep royal green leaves were as broad as my chest (which to be fair isn't all that broad, but it impressed me)!
All that to say Cottonwoods got some street creds when it comes to durability and resilience to disturbance.
As a counterpoint to this well-maintained Cottonwood, I am familiar with another ROW Cottonwood (same species) in town that stands alone in a large floodplain. This one has been absolutely mutilated by wind-damage over the years. Pretty much the entire crown has been ripped off in stages, save for two lower laterals where breakages have also occurred.
Species: Eastern Cottonwood (P. deltoides)
