Invasive Knotweed: info about proper control and disposal

 Thanks to Jay Held for sharing this King County brochure about stopping the spread of invasive knotweed. Knotweed destroys critical fish and wildlife habitat, displaces native plants, and also creates erosion problems along the riverbank.
Please be aware that knotweed spreads easily by even small fragments. Cuttings left by the side of the road or floating down the river may easily start new infestations.
See the brochure for more information about appropriate control and disposal of knotweed.
