Japanese knotweed (Fallopia japonica)

Japanese knotweed has become increasingly well known in recent years, particularly in the London area, and is a growing commercial problem because of the challenges it causes in the urban environment. The plant, which is native to eastern Asia, was introduced in the early 19th century to adorn the gardens of Victorian England. As early as the beginning of the 20th century it was widely recognized as an invasive species. Where the plant grows on development sites it can cause damage to hard structures and surfaces. Developers also often need to tackle the plant in order to avoid contravening the Wildlife and Countryside Act 1981.

Japanese knotweed is a common problem in London and you should take immediate action upon its discovery. Treatment can be lengthy and costly so the quicker you act the more effective is the control.

Don't cause the spread of Japanese knotweed stems and crowns. If you cut down Japanese knotweed, it is best to dispose of it on site.

Material taken off site is classified as waste and must be safely contained and disposed of at a licensed disposal site. The costs for correct disposal can be very high.

Don't try to dig up Japanese knotweed as this will lead to a significant increase in stem density. Even a tiny fragment of the cut rhizome is capable of regeneration.

Don't spread soil contaminated with Japanese knotweed rhizome.

Any soil that is obtained from ground within 7 m horizontally and 3 m deep of a Japanese knotweed plant could contain rhizome.

The rhizome is highly regenerative and will readily grow into new plants. Don't chip Japanese knotweed material. Mechanical chippers don't kill Japanese knotweed. If you spread the chipped material on soil, Japanese knotweed could regrow.

Don't dump garden waste contaminated with Japanese knotweed in the countryside - you will be breaking the law.

Don't add Japanese knotweed to compost. If you cause Japanese knotweed to spread you are guilty of an offence under the Wildlife and Countryside Act, 1981.
