What is Japanese Knotweed?

Japanese Knotweed ranks among the world’s most notorious invasive species, with its roots capable of penetrating hard surfaces like tarmac. Its presence poses a significant threat to both biodiversity and human activities. Consequently, prompt action is crucial upon identifying this invasive non-native plant on your premises to mitigate potential damage. 

Knotweed’s ability to infiltrate robust materials such as concrete flags, block paving, and tarmac underscores its destructive potential, even extending to buildings over time. Left unchecked, it can breach cavity walls, exacerbating structural concerns. While knotweed cannot directly penetrate concrete, it exploits any existing cracks, exacerbating surface damage. 

Early identification of the plant is crucial to minimise the extent of eradication efforts required. We offer complimentary on-site surveys, covering various plant species such as Japanese Knotweed, Giant Hogweed, and Himalayan Balsam. These species are categorised under schedule 9 of the Wildlife and Countryside Act 1981, and mismanagement can lead to project delays and escalated expenses.

Our expert team specialises in Japanese Knotweed management and eradication, ensuring effective control measures to safeguard your property. Should your site face an invasive plant species issue, we will provide you with a detailed report outlining the most cost-effective solutions available.

WHAT OUR CLIENTS SAY

“Incredibly grateful to SE Environmental for arranging an inspection and delivering a survey all within 24 hours of my getting in touch ahead of exchange on a house – impeccable service!”

- Charlotte

“Couldn’t recommend highly enough. Without the fast response of SEE we wouldn’t have been able to sell my house and buy our dream home. From the advice on the phone to the survey the next day and the report and management plan TWO HOURS after the survey was completed, the quality of service was faultless. I also couldn’t help myself searching for costs for both the initial survey and report and the treatment programme from other companies and SEE were the cheapest by far.”

- Jess

“I couldn’t recommend SE Environmental highly enough. I didn’t think I would be able to sell my house with Japanese Knotweed in the garden but a survey was able to be carried out the next day by a lovely chap and I had the management plan 3 hours after. The sale went ahead and I couldn’t be happier with the service.”

- Natalie

Japanese Knotweed FAQs

The Japanese Knotweed plant species (Fallopia japonica) originates from Japan, Korea, and parts of East Asia and China. It was introduced to the United Kingdom by the German-born botanist Philipp von Siebold in 1850, capitalising on the Victorian Britain’s enthusiasm for collecting and studying plants worldwide.

At one time, Japanese knotweed flowers and foliage were highly regarded for their beauty. In fact, in 1847, the Society of Agriculture and Horticulture in Utrecht described it as “the most captivating new ornamental plant of the year.”

Japanese Knotweed is non-native to Europe and was introduced to the United Kingdom without natural predators. Nevertheless, Knotweed adversely affects ecosystems by outcompeting native vegetation and diminishing the diversity of plant and animal species.

If you have Japanese knotweed growing near your home, retaining/garden wall, fence, or garden building, the underground roots and rhizomes can cause damage to these structures by exploiting cracks/mortar joints and vulnerabilities. Damage will occur as a result of the pressure exerted by the developing rhizomes.

Glyphosate-based herbicides have proven to be the most effective in controlling Japanese knotweed. Nevertheless, glyphosate is employed in a range of herbicides, with some exhibiting greater efficacy than others in eradicating Japanese Knotweed.
