— JAPANESE KNOTWEED REMOVAL OPTIONS AVAILABLE IN Havant

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

FOLIAR LEAF WIPING *
With this Japanese knotweed treatment, we use a device to “physically wipe” our chemicals onto the leaves of the Japanese knotweed. Due to the precision of this application, we can frequently employ a greater chemical concentration.

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 sort of excavation and removal, but instead of removing all of the soil affected by Japanese Knotweed, we simply remove the afflicted portions. It is an effective strategy for controlling Japanese Knotweed that permits the reuse of the soil. Reducing the amount of waste dumped in landfills.

CROWN REMOVAL
Removing the crown and stem from the equation is an excellent method since they can regenerate, and even small pieces of chopped crown or stem can regenerate and become a new invasive weed.

SOIL SCREENING
An effective technique utilised on hundreds of locations around the UK
The Japanese knotweed rhizome material is removed from the soil material using the screening procedure. The Japanese knotweed waste is then either burned on site with a D6 exemption from the Environment Agency or Natural Resources Wales, or it is transferred to a licenced landfill at a far reduced disposal rate.
After being cleaned, the soils can be used elsewhere, typically in soft landscaping areas where they won’t obstruct construction.
Due to fewer truck travels to the landfill, this can dramatically save landfill and backfill expenses while also assisting in lowering the carbon impact on the property.

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
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.
