FOLIAR SPRAYING *
The most common treatment for Knotweed is to spray it with powerful chemicals from a backpack. We ensure that other plants are not damaged in the process. The most effective time to spray for Knotweed is in early spring.

FOLIAR LEAF WIPING *
With this Japanese knotweed treatment, our chemicals are “physically wiped” into the leaves of the Japanese knotweed using a device. This application is so accurate that we can frequently employ a greater chemical concentration.

STEM INJECTION
We directly administer a measured amount of herbicide to the invasive weed. Due to the injection directly into the Japanese Knotweed, this is the most ingenious elimination technique. 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 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
To keep an eye on any digging or shifting of soil containing Japanese knotweed on your property, we can send a biosecurity worker.
We can set up a location where individuals can wash their boots and equipment at the site entry as a part of these precautions. We will supply the primary contractor with all toolbox discussions, which will be signed by all other contractors involved in the operation on site.
In locations where biosecurity is essential, we are able to offer temporary geotextile barriers.
After the service is over, we will deliver a thorough biosecurity report to the client.
This technique can be used in conjunction with other on-site therapeutic strategies.

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.
