Japanese Knotweed.
Japanese Knotweed
JKW, or Japanese knotweed, originates in Asia and grows according to environmental conditions. It was introduced by the Victorians as an ornamental garden plant.
There are no natural predators for Japanese Knotweed here in the UK, despite its rapid growth (up to 10 cm per day). Japanese Knotweed is believed to have the potential to erode brickwork when it is overgrown. This is because it exploits weak points in the brickwork, metal pilings, and even causing tarmac to become damaged when it is overgrown. It is generally believed that Japanese Knotweed poses a threat to buildings, even though it has never caused any serious subsidence cracks or structural damage. As a result of media hype, many unnecessary claims have been made against Surveyors, causing much distress to homeowners. You might have a difficult time selling your property if you find Japanese Knotweed on your property, regardless of the media hype. It is still possible for a mortgage company to offer funding on a property with a proper treatment plan and guarantee in place.
How to Identify Japanese Knotweed
A distinctive feature of this nuisance plant is its heart-shaped or spade-shaped leaves during the summer months. Japanese knotweed has zig-zag shaped stems from which the leaves grow, so you can spot it as the weather gets colder. It is, however, easy to mistake the plant for other shrubs. A cluster of white or cream-coloured flowers appears in late summer. This plant’s roots can spread several metres and are typically visible aboveground. Many homeowners, however, confuse Japanese knotweed with shrubs, trees, bamboo, bindweed or other ornamental shrubs. You should consult a Specialist if you suspect you have Japanese knotweed.
Removing Japanese Knotweed
Japanese knotweed is very difficult to eradicate; even 2mm cuttings can result in new growth. Under the Environmental Protection Act (Duty of Care) Regulations 1991, the plant is considered controlled waste and requires removal by a licensed waste carrier. In the absence of an adequate removal plan and guarantee, Japanese knotweed can pose a problem for a potential property buyer when applying for a mortgage. It is important to note that each lender has their own guidance when it comes to Japanese Knotweed and what needs to be done before lending on a knotweed-infested property.
