WHAT YOU NEED TO KNOW ABOUT THIS INVASIVE WEED IN SHEFFIELD
As Japanese Knotweed Infestations vary considerably from property to property, it’s not surprising that treatment and control will too. It may be necessary for one method of Japanese Knotweed treatment or a combination of different Japanese knotweed removal methods.
As this is an invasive weed, our Japanese Knotweed specialists are trained to factor in all considerations in order to achieve optimal results and removal. Decisions with regards to the methods of Japanese Knotweed treatment chosen will ultimately be decided by the ongoing assessment of site-specific factors/variables. A 10 year Insurance backed guarantee is available.
FOLIAR SPRAYING *
Most common treatment. The spraying of powerful chemicals with a knapsack. We ensure that other plants aren’t damaged. The most effective time for foliar spraying to Japanese Knotweed is in Spring
FOLIAR LEAF WIPING *
With this Japanese knotweed treatment we employ a device to ‘physically wipe’ our chemicals onto the Japanese Knotweed leaves. This application is so precise that we can often use a higher concentration of chemical.
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 form of excavation and removal but instead of extracting all of the soil impacted by Japanese Knotweed, we only remove the infested parts of the soil. It’s an excellent Japanese Knotweed control method that allows the reuse of the soil. Reducing the use of landfill.
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.
If you’re looking to develop or build on land that has Japanese Knotweed in Sheffield or South Yorkshire, a 5 year (herbicide) management plan is not recommended. A herbicide treatment will in most cases take too long to implement. Planners, workers, resource availability & financing schedules will require you to act quickly.
In cases of development, it’s also advised by the Environment Agency, that the entire rhizome of the Japanese Knotweed should be removed from the soil; and this is especially so when the ground is likely to be disturbed in the construction, building of, and extension of homes/industrial & commercial units & the landscaping of grounds.
We offer our clients professional Japanese Knotweed removal and options, all bespoke to the individual requirements of client. Our friendly and helpful staff are here to talk to, offering free advice & guidance. We guide you through the process, identifying the current use of the site, future plans for development and time-scales.
identify if planning applications have been submitted or approved (where planning has been approved we will ask you to provide copies to us, to aid us in deciding upon the best Japanese Knotweed removal approach) & advise the most cost effective solutions available.
Pictures, measurements and details specific to the site/project will be recorded – i.e. Access points for plant machinery, routes identified for disposal vehicles, potential bund areas identified & a Risk Assessment of the site and potential hazards recorded.
Factors such as nearby water courses, neighbouring properties & planning for the site will also contribute to the surveyor’s final conclusions when selecting the most cost effective and appropriate management plan for the site/project.
EVERY PROJECT IS DIFFERENT.
— TREATMENT OPTIONS AVAILABLE IN SHEFFIELD AND SOUTH YORKSHIRE
SOIL SCREENING
A tried and tested methodology used on hundreds of sites across 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 licensed 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 reused in locations away from any construction, normally in soft landscaping areas.
This can reduce the landfill & backfill requirement costs significantly and can also help to reduce the carbon footprint on site due to reduced vehicle movements to landfill.
BIOSECURITY SUPERVISION
Knotweed Services can provide a biosecurity operative to supervise any excavations and movement of soils containing Japanese knotweed on site.
As part of these measures, we can provide a biosecurity boot wash and machine-washing area installed in an area at the entrance to the site.
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 if required in areas to maintain the biosecurity on site.
Once the works have 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
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.
