Last June, NYS DOT surprised us by clearing the Japanese Knotweed along Rt 376 just north of Maloney, then applying enough defoliant to keep it knocked back this Spring:
A year earlier, they clearcut the overgrowth beyond the guide rail from Red Oaks Mill southward, but without defoliant, and the Knotweed is off to a good start:
I’ll do my part, inadequate though my pruners may be:
I got most of the growth in front of the guide rail extending across the shoulder, but must wait for another weekend morning to hack back the main stems.
Unfortunately, Knotweed control requires nearly continuous clearcutting and defoliation to prevent new growth.
