I live in Red Wing, MN. We have a cottonwood tree in our backyard. I believe it would be 25+ years old. It is about 60+ feet high. And 2.5 ft around lower trunk. I am wondering about the root structure. We have had several straight line winds these past few weeks and several dry stretches before that. Now several rainy periods of 2-4+ inches that fell in our area. We do not live by water, high above the MISSISSIPPI R. How can I continue to care for this tree? Reading about cottonwoods I understand there are male/female kinds. We have the cotton so I believe this is a female. And to look at it, it appears healthy and still green being September 21. (It had an Orioles’ nest this year). How can I help keep this tree healthy and sound?
