An August agriculture column urged local landowners to learn the signs of invasive knotweed.
Japanese, giant and Bohemian knotweeds were originally introduced from Asia as ornamental plants. They can now form dense stands that crowd out native vegetation and are difficult to remove once established.
Cutting or moving contaminated soil without a plan can spread stem and root fragments to new sites. Property owners should identify the plant carefully, avoid transporting fragments and consult current West Virginia extension guidance before choosing mechanical or chemical control.
