Japanese Knotweed

Japanese Knotweed (Fallopia japonica) is an extremely vigorous and invasive weed, introduced to the UK as an ornamental plant in 1825, and has become one of the most damaging and invasive species in Europe. 

Along with other invasive species, the control of Japanese Knotweed is a Europe-wide environmental concern and control of the species is covered by UK and European legislation.

Japanese Knotweed

Japanese Knotweed is known to damage structures, including walls and building foundations. Not only is it extremely difficult to get rid of, it thrives when disturbed. Small fragments of the plant, as small as 10 mm, can regrow to establish new growths. During the winter months, the plant dies back and may appear to be dead, but the root system (rhizome) is likely to be alive, continuing to grow below ground. As a result, all parts of the plant are considered as controlled waste making it very difficult for homeowners to dispose of cuttings.

The invasive nature of the plant and its potential to damage buildings means that where Japanese Knotweed is identified in a property purchase survey or home report, mortgage lenders often demand that the problem is professionally addressed.

Not many people are aware that it is illegal in the UK to cause Japanese Knotweed to spread from your property to your neighbours’ and so taking responsible action to control and remove growth is very important.
