. Male cottonwoods do not produce the cotton seeds.
Which is good news. The bad news is you can not tell the sex of the tree until it is older and large. The wind blows the female tree seeds far and seeds will clog air conditioners. The yard will grow lots of little trees. Cottonwoods are water lovers. They will put out roots in access of 40 feet looking for water, be careful of foundations, water, sewer or septic lines. They are excellent trees to plant in areas that accumulate standing water. Not good for hot and dry areas.
May you be blessed with a wonderful week!
