How to Get Rid of Knotweed
Japanese knotweed is one of the most damaging plants in the UK. Where it exists, the value of your property can drop by thousands – or even tens of thousands – of pounds. Wherever you are in the UK, we offer a free survey to discover whether you have knotweed on your property and how best to manage it.
If you own a commercial building or property, and Japanese knotweed is present, your project may be delayed until your infestation is being dealt with correctly and legally.
Here's how Japanese Knotweed can affect your life
- Knotweed can grow through tarmac and concrete, threatening the structural integrity of buildings.
- Lenders often deny mortgages against buildings affected by Japanese knotweed.
- Knotweed can grow so large and fast that it obstructs visibility and access to structures, such as paths, highways, and building facades. Knotweed can also be bothersome for commercial properties because it crowds out desirable crops.
For customers in St Helens with Japanese knotweed, Knotweed Services should be your first call. Each colony will be completely removed without damaging the surrounding area, and the removal will be insured in case of future re-growth.

What to Know About Japanese Knotweed Control in St Helens
Knotweed differs in size and severity from property to property, so treatment of the invasive plant will also vary from situation to situation.
We survey your knotweed problem and use the most effective methods for each growth stage, which allows us to deliver high-quality results that will produce a long-term solution. Our methods go beyond chemical treatments to identify root problems and prevent any future occurrences.
— JAPANESE KNOTWEED REMOVAL OPTIONS AVAILABLE IN St Helens
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 *
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
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 type of excavation and removal, but instead of taking out all of the soil, we only take out the parts of the soil that are infected. It’s a great way to get rid of Japanese Knotweed because the soil can be used again. Using landfills less often.
CROWN REMOVAL
Crown and stems are capable of regeneration, and even minute fragments of clipped crown or stem are capable of regeneration and producing a new invasive weed — eliminating these components is a wonderful technique.
Not in St Helens? No problem – we’re available throughout Greater Manchester and the UK.

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 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
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.
