Invasive knotweed control workshops to be held in Maple Valley, Duvall, Tukwila, Mercer Island and North Bend

Controlling invasive knotweed with a stem injector on Big Soos Creek

Our riparian team is once again offering multiple sessions of our popular free workshop called “What is knotweed and how can I get rid of it?”.  Participants will learn how invasive knotweed grows, how to control it, what’s being done on rivers in King County, and how to use and borrow a stem injector for use on their own land.

Sessions are scheduled on May 5 at the Maple Valley Library, May 11 at the Duvall Library, May 26 at Tukwila Community Center, June 2 at Mercer Island Community Center, and August 18 at Meadowbrook Farm in North Bend. All sessions are from 6:30 p.m. to 8:30 p.m. and share the same agenda. WSDA pesticide license recertification credits will be available.

As a bonus, all class participants can borrow our knotweed stem injectors for their own knotweed projects! The workshops are free and open to the public, but have limited capacity, so we ask everyone to register online. For more information, visit our website.
