Approximately one year ago, six locations in Gendringen were treated with our effective freezing method to treat Japanese knotweed.
The result is astonishing. In the soil, there are dead black rhizomes being decomposed by worms and insects. The once heavily infested area is hardly recognizable. There are no new shoots of Japanese knotweed to be found at these locations.
