About Japanese Knotweed

      • Japanese Knotweed is a perennial weed that will grow and spread very quickly if not treated and controlled
      • The weed suppresses all other plants and flowers growing around it and its crown and rhizomes (root system) spread extensively and unseen underground
      • The weed dies off above ground in winter and often people think it has gone, however, it will grow rapidly again from springtime through to early summer months, often in a larger area than it was in the previous year
      • Any well-established shoots can grow more than 9ft high and can colonize the soil within a few years
      • There are numerous articles that say you are able to kill the roots with chemical substances, however, you need an NPTC qualified person to work with any chemical substances and this is as a result of new legislation which covers the management, and removal of Knotweed
      • There are myths that say it is possible to remove Knotweed by digging it up, however, it is an extremely hard and complicated procedure and frequently, not successful unless you work with a Knotweed Specialist. Digging up Knotweed will spread it rapidly so always take extreme care when you are around it
      • In the height of its growing season, 60% of the Knotweeds roots are below ground making removal very challenging and it spreads wildly from one tiny fragment of crown or rhizome
      • Removing Knotweed without having extensive knowledge carries a very high risk of spreading the plant to other areas of the soil that have been previously unaffected

Treatment, Control & Removal of Japanese Knotweed

There are different options and ways of eliminating Knotweed and a professional specialist like ourselves will be able to give you advice on the best and most efficient approach for Japanese Knotweed Taunton Treatment, Control and Removal.

Stem-Injection is a low impact way of removal and there is little chance of disturbing or killing the plants and flowers growing about it. The stem-injection technique is used for smaller sized areas of Knotweed where it has established itself between plants and vegetation that you would like to keep. Additionally, it is an approach often utilised when Knotweed is in close proximity to a watercourse. The stem injection approach can be used in dry or inclement weather conditions and the soil can’t be disturbed following a treatment

Foliar Spray Application is often used and is among the most favourable control strategies as well as stem-injection. The process can be used to manage the Knotweed over numerous growing seasons. Dependent upon how large the area of Knotweed is it is normally sprayed 2-3 times in the first year and once in the following years. The chemical used is an Environment Agency approved herbicide and needs dry weather conditions as well as the soil to remain undisturbed in the following years to be effective

Weed Wiping Method is when the leaves of the plant are wiped with a sponge that is soaked with the required herbicide. This is a low impact treatment method and does not kill or disturb the plants encircling it, nevertheless, its use depends on the size of the area of knotweedBund/ Stockpiling Method is a combined treatment using stem-injection or foliar application, then digging up the underground material and removing the soil and materials to a different location in which the emergence of ‘new shoots’ can be subjected to further herbicide application. This approach is used on sites where you need the removal of the knotweed to be fast and not done over several seasons so is therefore specifically good for building plots and development sites as work can continue immediately

Cell Burial/Root Barrier Method is a treatment employed if you have enough space on-site to create a cell burial or making use of a root barrier to prevent the considerable expenses of transporting the soil and waste to landfill. Cell burial buries the Knotweed waste to a minimum depth, or if encapsulated inside a geo-membrane it can be closer to the surface of the ground. Root barriers can be installed both vertically and horizontally when there is a risk of cross-boundary contamination. Again, an approach most often used on development sites when construction work needs to commence promptly

Excavation & Removal Off-Site is a legitimate and quick control option that has its advantages for development sites if performed correctly, however, a great deal of Knotweeds Experts are not advocates of it simply because it raises substantial logistical complications. The challenges being it comes with an extremely high risk of the Knotweed spreading and also the cost to safely transport the material to a designated landfill site. There’s also substantial duty of care requirements under the Environmental Protection Act( EPA ) 1990. Excavation & Removal should only be used as an absolute last measure

Is Knotweed Poisonous to Dogs, Cats and Humans?

Essentially, Japanese Knotweed isn’t toxic and harmful to dogs, cats, people or any other animals like some other extremely invasive plants. It’s not harmful to touch, nonetheless, always employ extreme care when in close proximity to it to avoid inadvertently allowing it to spread.

Japanese Knotweed Taunton would probably be known as ‘poisonous’ by developers and homeowners due to the very invasive growth, the capability to spread from a tiny particle left and just how difficult it is to remove fully.

There are many contractors who operate within the UK weed control industry who are respectable, knowledgeable and who specialise in the control and management of Japanese Knotweed. There are, however, businesses that will claim to have the experience, qualifications and accreditations to ‘eradicate’/ ‘eliminate’ Japanese Knotweed at low cost. We would advise anyone to exercise caution and to always ensure that the service provider/ business they use to carry out the control programme are qualified to do so and that they adhere to the industry codes of practice. Contact us today if you think you may have Japanese Knotweed Taunton and we can come out and conduct a site assessment to identify it.

South West Knotweed Reports

Japanese Knotweed TauntonValidation Report – We conduct a site visit to assess and confirm if a particular plant is a Japanese Knotweed. Verbal confirmation to the client or a property prospective buyer is often sufficient, however, if we are initiated by a mortgage lender we can provide official confirmation in writing that is accompanied by a detailed estimate of potential remedial work.

We will document our findings as accurately as possible, however, under no circumstances will we be able to confirm absolutely that Knotweed material exists or doesn’t exist on a particular site. Knotweed can be easily concealed by cutting down, excavating, burning, or covering over, especially during the dormant season when there may be no visual indication. Our assessment will represent what we have seen since and our experience as it is impossible to see what lies beneath the surface. All Knotweed professionals in the industry will have this policy.

Site Assessment Report – The purpose of a SAR report is to provide clear guidance to a mortgage lender or purchaser regarding the level of risk involved due to the presence of Knotweed on, or near a property. We will provide an overview of the possible treatment options and we will map out locations or special features in order to determine whether Knotweed has damaged, or has the potential to damage any permanent structures on the site. The content of the SAR is normally reviewed by the mortgage lender in order to determine if there is or is not a significant risk in lending in line with their own individual policies.

Japanese Knotweed Management Plan (JKMP) – A JKMP is a detailed document including what the contractor must do to provide an appropriate treatment plan. It will include an overview of the control options available, a detailed assessment of the risks relating to any control action, and advice on biosecurity. The JKMP will be updated every year after treatment and evaluation and can be passed to any new owners.

We provide JKMPs for residential properties, plots intended for housing development, and large-scale development projects. In general, a JKMP is usually required by the mortgage lender before funds are provided for the purchase of a property. All our JKMP’s include a 10-year Insurance Backed Guarantee (IBG). The JKMP “stays” with the property, which means that whenever there is any future transfer of ownership, the JKMP goes with the new owner, no matter how many times the property trades hands.

Insurance Backed Guarantee -All of our JKMPs are accompanied by an independent 10-year IBG. The IBG gives you as our client, assurance that should we cease trading, the IBG will initiate a new contract with an accredited contractor to complete the remaining remedial work at no additional cost. Furthermore, should the Japanese Knotweed resurface from the original infestation site within 10-years of us issuing the Completion Certificate (see below) to the property owner, we will return to complete the remedial work, or if we are no longer trading, another accredited contractor will be paid to complete the work.

Completion Certificate – We provide every customer with a Completion Certificate to certify the treatment has been conducted and completed as per the legal guidelines. Once treatment has been completed in line with the JKMP, the completion certificate will be issued when there is clear evidence of 2 years of no recurrence of the Knotweed.
