Effective treatment of a range of invasive weed species across North West England

At Helmrig we offer a wide range of treatment options to many invasive weed species

Japanese Knotweed

Japanese Knotweed

In Europe the species is very successful and has been classified as an invasive species in several countries including the UK.

Himalayan Balsam

Himalayan Balsam is now widely established in other parts of the British Isles becoming an invasive species weed. The aggressive seed dispersal, coupled with high nectar production which attracts pollinaters, often allows the Himalayan Balsam to out-compete native plants.
