Japanese knotweed is a perennial, fast-growing invasive plant which can cause structural damage to homes and businesses, as well as disrupting the surrounding environment. It is also a significant threat to biodiversity, as it can grow rapidly and displace native plants. It is a prohibited species in the UK and it is illegal to allow it to spread across land without control.
Since its introduction to the UK in the 19th century, Japanese knotweed has grown rapidly. It has become an integral part of the British vernacular, with politicians referring to Theresa May as the “Japanese knotweed prime minister” and soccer legend Gary Neville bemoaning losing Manchester United players as “knotweed in a bag”. It is also known for its healing properties; it is an excellent source of the phenolic compound resveratrol which can improve organ https://www.japaneseknotweed.org.uk/ function and alleviate many common ailments.
It can spread quickly by rhizome growth and is notoriously difficult to eradicate completely. It has been found to encroach into neighbouring property, causing cracks in buildings and affecting drainage systems. Infestations can also impact on house values and it is a major reason why mortgages are often denied, as banks will not lend against properties where Japanese knotweed is present.
In addition to the physical damage that it causes, it can obstruct access roads and railways. Its roots have been known to exploit cracks in brickwork, railway sleepers and drainpipes, causing them to break and leak. It can also be a health hazard as it contains toxins that can harm pets and humans.
As a result, it is considered an invasive weed and is classified as such in many countries. It can be removed using various methods but it is important to choose a specialist who understands the issue and has experience in carrying out eradication works. It should be creditworthy, able to provide insurance backed guarantees (IBGs) and offer client funded accounts as these options give maximum financial protection to the consumer.
It is also worth checking that the company you use has undertaken the large scale research required to develop a treatment that will truly work. There are some companies offering treatment services that have never been scientifically tested, which is worrying. It is also important to look for a reputable company with the right credentials, such as membership of the Property Care Association and adherence to strict codes of practice.
