Invasive Knotweed Control Workshop
What is knotweed and how can I get rid of it?
Knotweed is a major problem in King County. This non-native, noxious weed chokes out native vegetation, increases erosion, degrades water quality and hurts habitat for fish and wildlife. It can also damage roads, pipes and building foundations.
This workshop teaches participants:
- How invasive knotweed grows and spreads
- How, when and where to control knotweed
- What is being done to fight knotweed on rivers in King County
- How to use and borrow a stem injector for use on your own land
- What opportunities for habitat restoration may be available for your own land
