We are specialists in Japanese Knotweed treatment and removal, as well as other invasive weed species.

Herbicide Treatment

Herbicide Knotweed Treatment

Folia (leaf and stem) Application

If you are looking for a treatment of Japanese Knotweed that is suitable for a large site then Herbicide is the answer. This is a great option if the site is not ecologically sensitive or subject to strict Japanese Knotweed treatment deadlines. This involves spraying the herbicide directly onto the foliage of the Knotweed to kill the plant.

Stem injection

Stem injection is an alternative to foliage spraying, which can affect other nearby plants. This Japanese Knotweed treatment involves injecting a concentrated dose of specialist Glyphosate Herbicide into each individual cane using equipment specifically designed for the treatment and eradication of Japanese Knotweed.

This is a good option if you wish to directly kill the Knotweed without harming any other plant species on the site.

Stem Injection



On large construction sites when work is in progress, the presence of Japanese Knotweed can cause costly delays to the building process. However, where possible, Japanese Knotweed can be relocated to a quarantined area of the site for treatment later, allowing work to progress as normal on the rest of the site. The Japanese Knotweed infestation can be treated with a chemical application at a later, more convenient time.

Root Barriers

If you are looking for a cost-effective Japanese Knotweed treatment then root barriers could be an option for you. As an alternative to removing Japanese Knotweed, it is also possible to halt its spread by using a Japanese Knotweed root barrier to prevent the growth of roots limiting its read and spread.

Sifting & Screening

Sifting and Screening

Another Japanese Knotweed treatment option to consider is excavating the contaminated soil. However, excavating the infested soil off-site for burial can become very costly as it is classified as controlled waste under UK law. The less contaminated soil you have though will help to lower the costs of the off-site burial.


Burning is one of the Japanese Knotweed removal methods that our experts use. Our specialist method and equipment ensure that the plant is fully incinerated to ensure full removal and to stop the infestation returning.

Vegetation and Tree Management

Trees and vegetation close to residential or commercial properties, power lines or on land accessible to the public need careful management to avoid risk to personal safety, or damage to buildings and other structures.

Landowners are responsible for the trees on their land and have a duty of care to prevent, as far as possible, injury to individuals and the destruction of property.

Wildlife Fencing

Wildlife fencing can be required both on existing residential and commercial property, new developments and rural environments, to protect animals who would be in danger if their habitat were compromised, or to prevent damage on specified areas of land by controlling wildlife movement. Our experts are on hand to provide specialist fencing to avoid such issues.

Japanese Knotweed Specialists provide ecological fencing services which will meet either requirement.
