Hi Susan,

Thank you for your question about eliminating aspen shoots. This is a very frustrating landscape problem, and a common issue in Central Oregon. Aspen roots are very vigorous. Aspens are genetically designed to be grove trees, so unfortunately, there is not much you can do to stop the roots from spreading. You can mow them down or pull and cut them out where possible, still, the shoots may continue to return.

For additional information, I recommend you call the Deschutes County OSU Extension office in Redmond at<personal data hidden>. Ask to speak with Amy Jo Detweiler (oregonstate.edu), our Community Horticulturist. Amy Jo welcomes your home garden questions and is a great resource. She may additional ideas for you.
