Unravelling the Mystery of Japanese Knotweed
Japanese Knotweed, is an aggressive and invasive weed that has spread throughout Warwickshire and the United Kingdom. This persistent plant features relatively broad, heart-shaped, green leaves that can grow up to 10 centimeters long.
In the late summer months, delicate white petals may emerge, adding a seemingly innocent charm to this otherwise destructive species.
As autumn arrives, the above-ground parts of the Japanese Knotweed wither and disappear, leading many to falsely believe that the plant has been eradicated. However, the roots of this invasive species continue to thrive and spread beneath the surface, secretly causing damage to the surrounding environment.
- Breaking Boundaries: The Relentless Growth of Japanese Knotweed.
One of the most concerning characteristics of Japanese Knotweed is its ability to grow through even the most robust barriers, including pavements and brickwork. As a result, its relentless expansion can lead to structural damage in both residential and urban settings.
The extensive root system of Japanese Knotweed is also known to block drains, causing issues with plumbing and potentially leading to costly repairs. - A Threat to Biodiversity: The ‘Carpet’ Effect of Japanese Knotweed
Japanese Knotweed’s invasive nature allows it to quickly create a dense ‘carpet’ effect, crowding out and suffocating other plant species. This can have a devastating impact on local ecosystems and biodiversity, as native plants struggle to compete with the rapidly spreading weed. - Landlords’ Legal Responsibilities and Neighborly Disputes
Legally, landlords are responsible for containing the spread of Japanese Knotweed on their property. Failure to do so can result in major issues with neighbors and even potential legal disputes, as the invasive plant encroaches on surrounding land. - The Financial Impact of Japanese Knotweed on Property Values
The stigma surrounding Japanese Knotweed is so pervasive that an afflicted property may lose up to 10 percent of its overall valuation. This drop in value can be attributed to the costly and time-consuming process required to effectively remove and control the invasive weed. - The Risk of Mortgage Declines
Due to the negative impact of Japanese Knotweed on property values and its potential to cause structural damage, mortgage lenders may be hesitant to approve loans for properties affected by the plant.
As a result, prospective homeowners may face significant challenges in securing financing for a property infested with Japanese Knotweed.

RESIDENTIAL TREATMENTS.
WHAT YOU NEED TO KNOW ABOUT JAPANESE KNOTWEED IN WARWICKSHIRE
The application method, treatment, and management of Japanese knotweed removal depend on the infestation levels. This invasive plant may necessitate one or more treatments.
To achieve optimal results, our Japanese knotweed removal experts are trained to consider all variables. Customized treatment strategies are developed based on continuous analysis of infestations unique to a specific site and the contributing factors.
The application process and control strategies will be tailored to individual locations to maximize efficiency while minimizing waste and environmental impact.
As PCA-approved Japanese knotweed removal specialists, we stay updated with the latest research to determine the ideal treatment timing. Trust in our eco-friendly solutions for effective removal.
The most recent study conducted at Swansea University, published in April 2018 by Dr. Dan Jones and Professor Dan Eastwood, revealed that:
Applying the wrong herbicides at the wrong time of the year, leads to greater herbicide use and environmental impacts. The 4-Stage Model that we have developed links herbicide selection and application with the seasonal surface-rhizome flows in the Knotweed plant. This seasonal targeting of Knotweed delivers better results and uses lower doses of herbicide across the whole treatment life-cycle. For the public and land managers, this means more affordable treatment that is also more environmentally friendly than traditional, blanket herbicide application.
Following the release of this research, Knotweed Services (UK) Ltd now operate using the 4-stage model which identifies the optimal time for treatment.
FOLIAR SPRAYING
The most commonly utilised treatment involves using a backpack sprayer to apply powerful chemicals. We exercise caution to avoid damaging surrounding plants. The ideal time for Japanese knotweed treatment is during the spring season.
FOLIAR LEAF WIPING
We use a specialised tool to “physically wipe” our chemicals onto the leaves of Japanese knotweed as part of this treatment. Due to its precise application, we typically use a higher concentration of chemicals.
STEM INJECTION
To eliminate the Japanese Knotweed, we use a highly innovative method where a precise amount of pesticide is directly injected into the weed. Since it targets the invasive plant specifically, this technique is considered the most effective. Additionally, this method is not affected by any weather conditions.
BIOMASS REDUCTION
Utilising biomass as a method of excavation and removal involves selectively extracting only the Japanese Knotweed-infected soil rather than removing all the affected soil. This exceptional treatment approach allows for soil reuse, ultimately contributing to a decrease in landfill utilisation.
CROWN REMOVAL
Eliminating the crown and stems of Fallopia Japonica is crucial as they can regenerate and even small fragments of these parts can sprout into new invasive weeds. Hence, removing them entirely is an effective method to eradicate the problem, ensuring that the roots of the Japanese Knotweed are completely eliminated.
COMMERCIAL REMOVAL.
Opting for a 5-year herbicide management plan is not feasible when planning to develop or construct on land infested with Japanese Knotweed. This is primarily due to the time restrictions faced by planners and construction personnel, as well as the limitations in resource allocation and financial timelines.
The Environment Agency recommends that, for development purposes, the entire rhizome of the Japanese Knotweed should be removed from the soil to achieve complete eradication. This is especially critical when the soil is expected to be disrupted during the construction, development, and expansion of residential, industrial, and commercial properties, as well as the landscaping of surrounding areas.
Knotweed Services (UK) Ltd provides expert services and tailored solutions to meet the unique requirements and expectations of each client. Our approachable and supportive team is readily available to address inquiries and offer guidance and assistance.
We will walk you through the process from the start, identifying the present use of the land, future
From the beginning, we will guide you through the process, taking into account the current land usage, future development objectives, timeframes, and schedules. We will also determine if any planning applications have been submitted or approved (if approved, we will request copies to aid in designing the treatment plan) and provide suggestions on the most cost-effective methods to address the issue, tailored to your project requirements.
We will document images, measurements, and specific details about the site or project, including access points for equipment, disposal vehicle routes, potential bund areas, and a risk assessment regarding the site and any potential hazards. In determining the most cost-effective and appropriate management plan, the surveyor will also take into consideration local rivers, adjacent properties, and site plans.
Upon completion of the site survey, a recommended action plan and cost estimate will be compiled into a report for the client to review and consider.
For every project undertaken, Knotweed Services (UK) Ltd supplies both the necessary equipment and skilled staff members. All of our technicians and operatives receive training and are directly employed by our company. We diligently oversee and manage each task, guaranteeing strict compliance with all regulations and preventing any cross-contamination. If you choose to supply your own machinery, we can also offer our supervision services for the project.
NO ONE JOB IS EVER THE SAME AS ANOTHER.
In reality most eradication programs are a combination of treatments.
— COMMERCIAL TREATMENT OPTIONS
SOIL SCREENING
Employed across thousands of UK locations, this methodology involves separating Japanese knotweed rhizomes from the soil through screening. The Japanese knotweed is either sent to an authorized landfill at a lower disposal expense or incinerated on-site in compliance with the Environment Agency or Natural Resources Wales D6 exemption.
The purified soil can then be utilised for soft landscaping purposes.
This approach can lead to savings on landfill and backfill expenses, as well as reduce a site’s carbon footprint, given that fewer trips to the landfill are required.
BIOSECURITY SUPERVISION
Knotweed Services can supply a biosecurity expert to oversee the excavation of Japanese knotweed.
We are able to set up a boot- and machine-washing station for biosecurity purposes at the site entrance.
All contractors will partake in a toolbox talk, signing for the site’s main contractor.
We can put in place temporary geotextile barriers in areas with elevated biosecurity risks.
Upon completion of the work, a biosecurity report will be sent.
This approach is suitable for on-site treatments.
EXCAVATION AND DISPOSAL
This treatment method is appropriate when time is of the essence, and it becomes necessary to transfer both Japanese Knotweed and contaminated soil to a permitted landfill.
By swiftly eliminating all traces of the infestation, the construction process can begin quickly. This method of Japanese Knotweed removal is the quickest and most effective way to destroy its rhizome system.
All off-site waste, including the root system of the invasive plant species, is transported to an authorised landfill by a licensed waste hauler.
CELL BURIAL
Moving Knotweed-contaminated soil from one site location to another and burying it in a trench enclosed with a root barrier membrane is cell burial.
Japanese Knotweed burial requirements:
- The Environment Agency proposes a 2-meter-deep burial chamber.
- The grave should be 5 metres deep.
- All root barrier seams are welded together to construct a cell Japanese Knotweed can’t escape. Backfill with clean soil.
- To minimise inadvertent disturbance of the burial site, all site designs should include its position.
STOCKPILE & TREAT
Bundling involves the transfer of contaminated Japanese Knotweed soil to a specific location. A bund refers to an area of polluted soil that is usually 0.5 metres deep.
The bund can be either raised or lowered to match the surrounding area’s appearance.
Japanese Knotweed is transported on bunds to vacant land, making it possible to treat the soil where it was previously impossible.
HERBICIDE APPLICATION
Knotweed Services can provide tailored treatment plans based on the location of the Japanese knotweed.
These techniques are compatible with treatments that limit pedestrian access, such as embankments or existing pathways.
This includes up to three visits annually for the application of herbicide through foliar spray or stem injection over a three-year period, followed by two years of monitoring.
We would choose herbicides based on the surrounding vegetation or environment.
After each visit, a detailed treatment record containing photographs of the site’s progress and an annual report are provided. This solution is most effective during the growth season.
