The Usual Suspects

Several plants are often mistaken for Japanese knotweed due to similar appearances, leading to unnecessary alarm. These include Bindweed, which has heart-shaped leaves and white or pink trumpet-shaped flowers. The Himalayan balsam, another common misidentification, has leaves similar to the knotweed but distinguishes itself with its purple or pink flowers.

Another plant is the Bamboo, having cane-like stems similar to the Knotweed, but its leaves are much thinner and longer. The Russian Vine also shares some characteristics, with its heart-shaped leaves and white flowers, but it is a climbing plant unlike the erect Knotweed.

Lastly, Dogwood, specifically the Red Barked Dogwood, can cause confusion with its red stems, but its flowers and leaves are vastly different. Always consult with an expert if you’re unsure about plant identification.

It is not illegal to have Japanese knotweed on your land and you do not have a legal duty to notify anyone that you have Japanese knotweed on your land.

However, there are laws which cover the spread and transport of Japanese knotweed, and without taking action it is possible that you may commit an offence, or be liable for action in the civil courts (you could be sued).

It is an offence under the Wildlife and Countryside Act 1981 to plant or cause Japanese knotweed to grow in the wild. Prosecutions are very rare, however, and JKSL are not aware of any charges brought under this legislation for allowing Japanese knotweed to spread into a domestic property.

Japanese knotweed (and soil or other material containing Japanese knotweed) is considered “controlled waste” under the Environmental Protection Act 1990. This means that if you move Japanese knotweed off your land there are various legal duties in how the waste is managed. Controlled waste can only be taken to licensed landfill – this is expensive, the material needs to be booked in with the landfill and there are limited sites which will accept Japanese knotweed materials.


You do not have any legal responsibility to treat Japanese knotweed – however (as outlined above), there are laws which cover what you must, can and cannot do with Japanese knotweed material.

In addition, there have been cases in the civil court where neighbours have been successfully sued for damages for allowing Japanese knotweed to affect adjacent properties.

Local authorities have the power to issue a “community protection notice” (CPN) to compel you to treat Japanese knotweed if it can be shown that you are causing an impact on “local amenity” through your failure to treat or manage the plant.

A Bristol company was prosecuted and fined £18,000 plus costs in 2018 for failing to comply with a CPN which ordered the control of Japanese knotweed on their land. The company was also ordered to secure a management plan from a specialist company within a month of the judgement.


Japanese knotweed is not the most damaging of plant species – but it can grow through tarmac and through small gaps or weaknesses in paving, concrete and other surfaces.

Where construction works are carried out in areas where Japanese knotweed is present, we have seen cases where the plant grows up through floorboards, or between gaps between the old and new construction, resulting in Japanese knotweed plants growing inside a house or commercial building. When this occurs, treatment becomes significantly more complex.
