FOLIAR SPRAYING *
Foliar spraying is the most common treatment for Japanese knotweed. We ensure that other plants aren’t damaged while treating Japanese knotweed, and perform foliar spraying in the springtime.

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 inject a precise dose of herbicide directly into the invasive weed. This is the most devious way of elimination because it is injected straight into the Japanese Knotweed. It is not affected by the weather.

BIOMASS REDUCTION
Biomass is a sort of excavation and removal, but instead of excavating all of the soil affected by Japanese Knotweed, we simply remove the afflicted portions. It is an effective method of Japanese Knotweed control that allows for the reuse of the soil. minimising landfill usage.

CROWN REMOVAL
Crown and stems are capable of regenerating and even small fragments of cut crown or stem are capable of regenerating and becoming a new invasive weed – removing these from the equation is a great strategy.

SOIL SCREENING
A tried-and-true strategy utilised on hundreds of sites across the United Kingdom.
Using screening, the rhizome material of Japanese knotweed is removed from the soil material. The Japanese knotweed material is then either transferred to a licenced landfill at a significantly reduced disposal rate or burnt on-site with an Environment Agency or Natural Resources Wales D6 exemption.
The cleansed soils can then be reused elsewhere, typically in soft landscaping areas where they will not interfere with construction.
This can greatly minimise landfill and backfill expenses and assist lower the site’s carbon footprint by reducing the number of vehicle trips to the dump.

BIOSECURITY SUPERVISION
Knotweed Services can provide a biosecurity operative to supervise any excavations and movement of soils containing Japanese knotweed on site.
As part of these measures, we can provide a biosecurity boot wash and machine-washing area installed in an area at the entrance to the site.
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 if required in areas to maintain the biosecurity on site.
Once the works have 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.
