The Roanoke Tree Care Workshop usually takes place in March in partnership with VA Department of Forestry and Roanoke Valley Urban Forest Council made up of representatives from the surrounding municipalities, regional commission and private partners. These workshops pull hundreds of attendees throughout the state and mid-Atlantic to share knowledge and the latest best management practices in tree care.
