Japanese knotweed (Fallopia Japonica) is one of the world’s most invasive plants. It is found throughout the UK, blighting landscapes and causing major problems for homeowners, businesses and developers alike. It can devalue properties and in some cases cause mortgage lenders to refuse lending where it is present on a site. It can also be very difficult to clear if left untreated.
For these reasons, anyone who has a Japanese knotweed problem should contact a specialist. The right japanese knotweed specialists will be able to draw up risk assessments and treatment plans that are accepted by mortgage lenders. They will be able to offer insurance-backed guarantees that ensure a positive resolution to the issue.
The key to treating Japanese knotweed is to remove the rhizomes that give rise to new shoots. This can be done using a range of different approaches, including digging, excavation, burning and herbicides. Most companies will offer a combination of these treatments, and will work over a number of years to achieve the desired result. It is important to find a company that is reputable and ideally member of the Property Care Association’s Invasive Weed Control Group or Trustmark Government Endorsed Standard (for commercial site development).
Another important factor in finding a good Japanese knotweed specialist is to make sure they have public liability insurance, preferably cover of 5m or more. It is also important to find out if they have professional indemnity insurance, again ideally with cover of 1m or more. Finally, the right specialist should be able to offer an insurance-backed guarantee of up to 10 years, to provide peace of mind for their clients.
A good Japanese knotweed specialist will be able to offer the right solution for your specific needs, and will be able to discuss your options over the phone. They will also be able to verify the identification of the plant and carry out an initial homeowner survey free of charge.
Small clumps of Japanese knotweed can usually be removed by home gardeners by digging or spraying with weedkiller. Larger infestations require a professional, as they are much more difficult to treat. Professionals can also draw up a management plan that includes a guarantee of eradication, which is generally accepted by mortgage lenders.
It is important to note that it is against the law to add Japanese knotweed to home compost or council-run garden waste bins. It is also illegal to dump it on the ground, and should only be placed in licensed landfill sites. It is also recommended that you hire a Japanese knotweed specialist with the correct certification to ensure that they are qualified and experienced in dealing with this invasive species. They should be able to supply proof of their qualifications and membership of the appropriate industry bodies. The best companies will also be able to provide a comprehensive service, covering all aspects of the Japanese knotweed removal process. They should be able to offer full site surveys, excavation and treatment and a range of insurance-backed guarantees.
