Understanding the Threat: Japanese Knotweed in Sheffield

Japanese Knotweed (Fallopia japonica) is a highly invasive plant species that poses a significant threat to the ecological balance and structural integrity of urban areas, including Sheffield. This fast-growing perennial plant, originating from East Asia, has rapidly spread across the globe, demonstrating its resilience and adaptability. Its presence can cause extensive damage to buildings, roads, and other infrastructure, leading to costly repairs and decreased property values.

Characteristics of Japanese Knotweed

Japanese Knotweed exhibits astonishing growth rates, with some shoots reaching up to 10 centimetres per day. This rapid growth enables the plant to quickly colonise new areas and outcompete native plant species. The root system of Japanese Knotweed can extend several metres below the ground, spreading horizontally over a wide area. These extensive roots make complete eradication of the plant challenging.

Impacts of Japanese Knotweed in Sheffield

Japanese Knotweed presents several significant challenges to Sheffield’s urban environment. The extensive root system of Japanese Knotweed can penetrate cracks in walls, pavements, and foundations over time. As the plant grows, it exerts pressure on vulnerable areas, exacerbating existing issues and potentially compromising the integrity of buildings and infrastructure.

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.
