Weed Control

Through years of hard work installing, maintaining, and monitoring restoration projects in western Washington and northwest Oregon, we have determined what weed control methods work the best. Our invasive plant management plans emphasize using manual control methods and establishing a competitive native plant community. Sound Native Plants has crews based in Olympia and Vancouver/Portland that perform weed control and other maintenance tasks.
