HIS screened upwards of a thousand tons of soil for Japanese Knotweed rhizomes at Highwood Construction’s site at Fareham, near Portsmouth over two weeks in late October. See pictures Example project n.1 here.

We used the cell burial/encapsulation technique during early November to protect Elldan Properties’ Huntley Lodge development in Peterborough against Japanese Knotweed to save the cost of landfill.

HIS applied end of season herbicide treatments to various sites around the UK over the last month against Japanese Knotweed, Himalayan Balsam, Giant Hogweed and Ragwort.
