WHAT YOU NEED TO KNOW ABOUT JAPANESE KNOTWEED REMOVAL Portsmouth

As Japanese Knotweed infestations vary widely from property to property, it’s unsurprising that treatment and control will too. It may be necessary to use one treatment method or the combination of different techniques for eradicating Knotweed.

We take a scientific approach to weed control. Our weed specialists examine a site’s specific factors to determine the type of treatments that will give the best results. We guarantee all our work.

— JAPANESE KNOTWEED REMOVAL OPTIONS AVAILABLE IN Portsmouth

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 treatment for Japanese knotweed, we use a tool to “physically wipe” our chemicals onto the plant’s leaves. Because of the accuracy of this application, we frequently allow a higher chemical concentration.

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 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 can regenerate, and even small bits of chopped crown or stem can regenerate and become a new invasive weed; removing these from the equation is a fantastic method.

SOIL SCREENING

A tried-and-true methodology used on hundreds of sites throughout 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 a licenced 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 used elsewhere, usually in soft landscaping areas, where they won’t be in the way of building.

This can significantly reduce landfill and backfill costs while also helping to reduce the carbon footprint on site due to fewer vehicle movements to the landfill. 

BIOSECURITY SUPERVISION

We can send a biosecurity operator to your property to monitor any excavations or movement of Japanese knotweed-containing soil.

As part of these steps, we can set up a location near the site’s entrance where people can wash their boots and machines. We will supply the primary contractor on site with all toolbox discussions, which will be signed by all contractors involved in the operation.

In situations where biosecurity is necessary, we may provide temporary geotextile barriers.

We will supply the client with a thorough biosecurity report once the service is concluded.

This procedure can be used in conjunction with other on-site treatment methods.

Commercial Japanese Knotweed Excavation

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.

Japanese Knotweed Cell Burial

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 

Bundling is a technique used to move contaminated Japanese Knotweed soil to another portion of the site that is being treated. A bund is a small, often 0.5m-deep region of contaminated soil.

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.

The Japanese Knotweed will be relocated to a less-used region of the site thanks to the bund. When compared to where the Japanese knotweed was first found, this “buys time” for treatment.

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.
