Japanese Knotweed is an invasive, fast-growing and highly resilient perennial plant species originating from Japan, and typically is found growing around volcanoes.

Introduced to the United Kingdom in the 1800s as an ornamental plant, it grows into dense stands which out-compete other native plant species.

Japanese Knotweed starts to die back in late autumn and is dormant throughout the winter months. The dry dead canes however, are often intact until the following growing season and beyond.

In accordance with the Wildlife and Countryside Act 1981 it is an offence to allow Japanese Knotweed to grow in the wild.

The value of your property could also be diminished by up to 10% if it is affected by Japanese Knotweed and it may cost thousands of pounds to eradicate.

Most mortgage lenders will refuse to grant mortgages on properties that are affected by Japanese Knotweed and many prospective buyers are reluctant to purchase properties affected by it.
