FOLIAR SPRAYING *
Spraying of powerful chemicals with a knapsack is the most common treatment for Japanese knotweed. We ensure that other plants are not damaged when spraying, and we spray only in 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 type of excavation and removal, however instead of extracting all of the soil impacted by Japanese Knotweed, we simply remove the afflicted areas of the soil. It’s an outstanding Japanese Knotweed control approach that enables for soil reuse. Reducing the use of landfill.

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 tested methodology used on hundreds of sites across the UK.
Using the screening method, the Japanese knotweed rhizome material is separated from the soil material. The Japanese knotweed material is then either transported to licensed landfill at a much lower disposal rate or incinerated on site using a D6 exemption from the Environment Agency or Natural Resources Wales.
The cleaned soils can then be reused in locations away from any construction, normally in soft landscaping areas.
This can reduce the landfill & backfill requirement costs significantly and can also help to reduce the carbon footprint on site due to reduced vehicle movements to landfill.

BIOSECURITY SUPERVISION
We could send a biosecurity operative to monitor any excavations or movement of Japanese knotweed-containing soil on your property.
As part of these steps, we can set up a location at the site’s entry where people can wash their boots and machines. We will offer all toolbox discussions for the primary contractor on site, which will be signed by all contractors involved in the operation on site.
We may provide temporary geotextile barriers in situations where biosecurity is necessary.
We will present the client with a comprehensive biosecurity report once the service is concluded.
This procedure can be used in conjunction with other on-site treatment options.

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
Japanese knotweed-contaminated soil can be moved to another portion of the site being treated using a technique called bunding. A bund is a patch of polluted soil that is only a few metres deep.
To make the surface flush with the surroundings, the bund can either be lifted, placed on top of the land, or positioned inside an excavation.
The bund’s function is to relocate the Japanese knotweed to an inactive portion of the land. The Japanese knotweed may now be treated, which would not have been possible in its original location.

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.
