The problem with Japanese knotweed

Japanese knotweed (Fallopia Japonica syn. Polygonum cuspidatum) is a highly invasive non-native weed that can damage foundations and driveways, as well as putting a stop to mortgage applications and construction development plans. First introduced to the UK from Japan in the 1840s as an ornamental plant, Japanese knotweed is now widespread throughout the UK and can be found as a wayside weed and in many private properties across the country. In spring, the bamboo-like stems grow at a rapid rate, reaching up to 2 metres in height. In summer, the plant produces creamy white flowers. Don’t be fooled by its beauty, as Japanese knotweed can quickly dominate the landscape, suppressing all other growth and damaging properties. Over the winter, the above ground growth dies back but the underground rhizome root system remains alive, ready to grow again in spring.

Mortgages lenders require a Japanese knotweed management plan with an insurance backed guarantee to be in place before they will lend on properties with this prolific perennial. Knotweed has the ability to cause significant damage to tarmac, concrete, paving slabs and foundations of properties. Eradication and Japanese knotweed removal requires expertise. It is very difficult to remove by hand, because the rhizome root system extends deep into the ground. Chemical treatment methods require expert application in order to kill Japanese knotweed. There are also various legal considerations when dealing with Japanese knotweed. Private nuisance claims can be brought against a landowner who allows knotweed to spread into adjoining land. Under the provisions made within the Wildlife and Countryside Act 1981, it is an offence to cause Japanese knotweed to grow in the wild.

Japanese knotweed identification help

Support our chosen charities with Japanese knotweed identification

Japanese knotweed is the UK’s most aggressive and invasive plant, however it can be tricky to identify.

Commonly confused for plants such as Russian vine and bamboo, knotweed wreaks havoc when it comes to buying or selling a property, and can create issues between neighbours. It is especially hard to identify over the winter, as the knotweed lies dormant waiting to re-emerge in the spring.
