Unknown invasive grass?
Hello. This grass has developed in my neighbor's lawn this past season. It has taken over most of her lawn and now coming into mine. It is bright green grows very tall very quickly. It has a short root system that pulls out very easily. Can you tell me what it is and how to stop it from coming into my lawn?
