— JAPANESE KNOTWEED REMOVAL OPTIONS AVAILABLE IN Sefton

FOLIAR SPRAYING *
The most common treatment is the spraying of powerful chemicals with a knapsack. We ensure that other plants are not damaged. The most effective time for foliar spraying is in Spring.

FOLIAR LEAF WIPING *
We use a device to ‘physically wipe’ our chemicals onto the Japanese knotweed leaves in this Japanese knotweed treatment. Because this use is so exact, we can frequently use a higher concentration of chemical.

STEM INJECTION
A measured amount of herbicide is applied directly to the invading plant. This is the most ingenious way of elimination because the herbicide is injected straight into the Japanese Knotweed. Not dependant on weather conditions.

BIOMASS REDUCTION
Biomass is a type of excavation and removal, but instead of extracting all of the Japanese Knotweed-affected soil, we simply remove the afflicted soil. It is an outstanding Japanese Knotweed control strategy that enables for soil reuse. Reducing landfill usage.

CROWN REMOVAL
Crown and stems are capable of renewing, and even small fragments of clipped crown or stem are capable of regenerating and producing a new invasive weed – eliminating them is a wonderful method.

SOIL SCREENING
A tried-and-true methodology utilised on hundreds of sites across the UK.
The rhizome material of Japanese knotweed is removed from the soil material using the screening procedure. The Japanese knotweed debris is then either transferred to a licenced landfill at a significantly reduced disposal rate or burnt on site using a D6 exemption from the Environment Agency or Natural Resources Wales.
The cleaned soils can subsequently be used elsewhere, typically in soft landscaping areas where they will not interfere with construction.
This can greatly cut landfill and backfill expenses while also helping to minimise the carbon impact on site due to fewer truck travels to the dump.

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 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.
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.
For the surface of the bund to be flush with the surroundings, it can be raised, placed on top of the ground, or positioned inside an excavation.

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.
