Under new proposals from the government, people who fail to control Japanese Knotweed or other similar non-native invasive plants, can be fined.

The fines can be up to £2500 for an individual or £20,000 for a company that fails to take action against plants such as Giant Hogweed and Himalayam Balsam.Japanese Knotweed 800

The Home Office says these plants threaten the UK’s biodiversity by crowding out native species and destabilising river banks. They can also do immense harm to forestry, farms, roads and buildings.

Damage Caused

Japanese Knotweed can grow through tarmac and cause structural damage to properties, while giant hogweed can create serious health problems for humans, such as blisters, skin diseases and even blindness.

Japanese knotweed is particularly difficult to eradicate. It is very resilient and regrows vigorously after being cut down. Treatment has generally been carried out using spray treatment to the plants through the growing season. Because of the depth that the roots spread down through the ground other treatments such as digging out have proved to be very expensive, and many disposal sites refuse to handle lorry loads that contain Japanese Knotweed.

Our Treatment

TR Landscape Contracting are now using the latest Stem Injection Techniques that involve injecting chemical, normally Glyphosate, directly in to the stem of the plant. This is not only better for the environment as the risk of spray drift or run off is reduced, but has proved to be a far more efficient method of eradication. Instead of the previous method requiring treatment programmes that could be spread over several years we now see effective treatment carried out in only 12 months. As many of the sites we work on are earmarked for future development this reduced treatment time is beneficial as planning approvals and mortgage funding can be delayed on sites where invasive weeds are present.

However, our treatment can also include ongoing monitoring of previously infested areas to ensure that the work we have done is a success.
