- The invasive plant Japanese Knotweed can grow through tarmac and concrete, posing a structural threat to buildings.
- If Japanese Knotweed is present in a property, mortgage lenders often refuse to lend against that property.
- Knotweed is a pest that obstructs both visibility and access to paths, highways, and other infrastructure. Producinga massive annoyance for commercial properties in particular.

WHAT YOU NEED TO KNOW ABOUT JAPANESE KNOTWEED REMOVAL Plymouth
Japanese knotweed infestations vary widely from property to property, so it’s not surprising that treatment and control methods will too. It may be necessary to use one method or a combination of knotweed removal methods on one property.
Japanese knotweed is a complicated problem, but our specialists are trained to treat it effectively. They must consider many factors in determining the best ways of removing it. An insurance-backed guarantee is available for all of our work.
— JAPANESE KNOTWEED REMOVAL OPTIONS AVAILABLE IN Plymouth

FOLIAR SPRAYING *
The most commonly used method of treating Japanese knotweed is with herbicide. This is done by spraying the plant with a knapsack sprayer in early spring.

FOLIAR LEAF WIPING *
With this Japanese knotweed treatment we employ a device to ‘physically wipe’ our chemicals onto the Japanese Knotweed leaves. This application is so precise that we can often use a higher concentration of chemical.

STEM INJECTION
We apply a controlled amount of herbicide directly into the invasive weed. Due to being injected directly into the Japanese Knotweed, this is the most crafty method of removal. It isn’t dependent on the weather.

BIOMASS REDUCTION
Biomass is a form of excavation and removal but instead of extracting all of the soil impacted by Japanese Knotweed, we only remove the infested parts of the soil. It’s an excellent Japanese Knotweed control method that allows the reuse of the soil. Reducing the use of landfill.

CROWN REMOVAL
Crown and stems are capable of regeneration, and even minute fragments of clipped crown or stem are capable of regeneration and producing a new invasive weed — eliminating these components is a wonderful technique.

SOIL SCREENING
A tried-and-true system that has been utilised on hundreds of sites across the UK.
The Japanese knotweed rhizome material is removed from the soil material using the screening procedure. The Japanese knotweed debris is then either transferred to a licenced landfill at a substantially reduced disposal rate or burnt on site using an Environment Agency or Natural Resources Wales D6 exemption.
The cleaned soils can subsequently be used elsewhere, mainly in soft landscaping areas where they will not interfere with construction.
Due to fewer vehicle transfers to the landfill, this can greatly minimise landfill and backfill expenses while also helping to reduce the carbon footprint on site.

BIOSECURITY SUPERVISION
We can provide a biosecurity operative to monitor any excavations or movement of Japanese knotweed-containing soil on your property.
As part of these measures, we can set up a place at the entrance to the site where people can wash their boots and machines. We will provide all toolbox talks for the main contractor on site, which will be signed by all contractors involved in the operation on site.
We can provide temporary geotextile barriers in areas where biosecurity is required.
Once the work has been completed, we will provide the client with a full biosecurity report.
This method can be used in conjunction with other treatment methods on site.

EXCAVATION AND DISPOSAL
This treatment method is ideal where time constraints are present and there’s no other option other than to remove both the Japanese Knotweed and contaminated soil to a registered landfill.
By removing all traces of the infestation quickly, this offers a rapid solution to your problem and allows your commercial project to begin groundwork’s almost straight away. When time is of the essence, there is no quicker Japanese Knotweed removal/treatment method.
Any waste taken off-site will be done so with a licensed waste carrier to a suitably authorised landfill site.

CELL BURIAL
Cell burial comprises of moving Knotweed contaminated soil from one location on site, burying it in an excavated pit which is lined with a root barrier membrane, in a different position on the site.
The burial requirements for Japanese Knotweed are as follows:
- The Environment Agency recommends that the top of the burial cell should be a minimum of 2 metres below ground level.
- The overall depth of the burial pit should be in excess of 5 metres deep. All root barrier seams are welded together forming an encapsulated cell from which the Japanese Knotweed cannot escape. Clean soil is then used to backfill on top of the cell.
- To prevent accidental disturbance of the burial site, it is recorded on all site plans and future land owners should be made aware of the location.

STOCKPILE & TREAT
Bunding is the method of relocating contaminated Japanese Knotweed soil to a different area of the site being treated. A bund is a shallow area of the contaminated soil, typically 0.5m deep.
The bund can either be raised, on top of the ground, or placed within an excavation to make the surface flush with the surrounding area.
The purpose of the bund is to move the Japanese Knotweed to an area of the site that is not used. This ‘buys time’ for treatment that would not be possible where the Japanese Knotweed was originally located.

HERBICIDE APPLICATION
At Knotweed Services we can provide the client with bespoke treatment plans depending on the locations of the Japanese knotweed.
These plans can work in conjunction with other methods of treatment where access is limited to pedestrian movements i.e., embankments or existing pathways within a site.
This will normally consist of up to 3 visits per annum to apply herbicide by either foliar spray technique or stem injection during the growing season over a period of 3 years, with a monitoring period of 2 years thereafter.
We would select the appropriate herbicides depending on the surrounding foliage or environmental constraints.
After each visit a full treatment record would be provided with photos showing the progress of the works and then an annual report.
