How do I get rid of Japanese Knotweed?

When dealing with Japanese Knotweed there are important legislation and protocols that must be followed to ensure effective control. We have a robust and consistent approach that has successfully protected properties and land against Japanese Knotweed time and time again.

IDENTIFICATION The plant has key characteristics at each stage of its growth cycle which our surveyors are specifically trained to recognise. 

SURVEY Our expert surveyors will conduct a comprehensive survey and provide a report which will include detail of invasive plant species found, survey images, mapped location of Japanese Knotweed, recommendations on treatment options and a written quotation.

MANAGEMENT PLAN We offer tailored solutions to combat any Japanese Knotweed problem and will advise on the best option for your property.  Our management plan documents comply with PCA standards and assist homeowners when applying for mortgages.

TREATMENT OR REMOVAL Our remediation strategies include herbicide treatment, root barrier membranes, stockpiles and excavation with offsite disposal.

MONITORING & AFTERCARE On completion of the treatment or excavation we will continue to monitor the site for a period of up to 2 years to ensure complete control has been achieved.

Most lenders and insurance providers require a management plan to be in place before they will make any offers. The sooner that Japanese Knotweed is detected and treatment started the better for all landowners.

Removing Japanese Knotweed is not as simple as digging it out and putting it in the bin.  It is classified as ‘controlled waste’ therefore its removal and disposal should be managed by a licensed contractor only. Japanese Knotweed treatment options will depend on what the land is to be used for, timescales, cost and environmental implications. Herbicide treatment options are generally suitable for homeowners who can allow for longer treatment times (usually 2-5 years) and are a cost-effective method. Excavation provides a much faster eradication (completed within weeks) and is often necessary on construction and development sites. We have the experience, qualifications, and licenses necessary to provide these services across the UK.

Following completion of the treatment phase, we then provide ongoing monitoring for up to 2 years to ensure the affected areas are clear from rhizomes (roots). Bespoke aftercare plans can be discussed and arranged when developing the management plan.

Let the experts at JBB Knotweed Solutions advise on the best management plan for you and carry it out with the care and professionalism we are known for.

Stem Injection & Leaf Application

Stem Injection provides a targeted treatment using concentrated doses of herbicide which are injected directly into the plant’s stems using specialised equipment. The herbicide is drawn down through the stem and penetrates deep into the rhizomes where it kills the plant. This method of control is particularly advantageous due to its lower environmental impact.

5. Excavation with offsite disposal (main image)

Excavation and Off-Site
Disposal

Land contaminated with Japanese Knotweed can prove troublesome to developers and construction firms whose projects may be hindered until the knotweed is dealt with. Homeowners looking to build an extension or have their garden landscaped may require an immediate solution.

6. Excavation with onsite treatment

Excavation and On-Site
Treatment

On sites where additional space is available, excavated waste can be stockpiled in a segregated area where its presence will not pose any threat to surrounding structures or be at risk of spreading. A suitable management plan can then be put in place to treat the Japanese Knotweed with herbicide over a period of 2-5 years.

7. Root Barriers

Root Barriers

Root barrier membranes can be used as a means to prevent the spread of Japanese Knotweed onto neighbouring land.  The effectiveness of the membrane is determined by good installation, therefore, it is essential that a specialist contractor such as JBB Knotweed Solutions is involved to undertake the task. A failure to halt Japanese Knotweed from spreading onto neighbouring property could result in legal proceedings.
