What is Japanese Knotweed?
Japanese Knotweed (Fallopia Japonica) is an invasive and impinging perennial plant that colonises large areas of land with its deep penetrating roots known as rhizomes, it spreads quickly and uncontrollably if it is not treated, and can cause problems for buildings and native woodland species due to the incursive nature of its root system.
The plant was first introduced to the UK in the mid-nineteenth century and was very popular amongst Victorian gardeners due to its fast growth, heart shaped leaves and white flowers. Over time Japanese Knotweed has spread throughout the country through purposeful planting to stabilise loose soil, gardeners sharing cuttings and the unlawful disposal of contaminated garden waste.
Japanese Knotweed is now one of the major environmental issues that faces the UK as the species can grow though tarmac and damage foundations which causes significant structural damage to property and infrastructure. Property and landowners have a legal responsibility to prevent invasive non-native plants, such as Japanese Knotweed from spreading into the wild. This particular species of plant must be removed, treated and disposed of in accordance with current government legislation and the PCA Code of Practice.
