Did you know trees can be considered noxious weeds? The City of Seattle is revising some of its tree rules regarding tree protection, and one item on the docket is to exclude any tree on the King County Noxious Weed List from being classified as an exceptional tree. One of the most wanted noxious weeds on the list, tansy ragwort (pictured here) is in full bloom right now and very easy to identify and control. In addition to our arborist credentials, we are licensed Washington State Department of Agriculture Pesticide applicators and can help you identify and control noxious weeds on your property.
