Suspect Japanese Knotweed? Get it identified by trusted experts now!

Japanese Knotweed was first introduced in the UK in the 1850s as a decorative, ornamental plant. It was used to help stabilise railway embankments and cuttings as well as highway infrastructure. Nowadays it is classed as an ‘Invasive non-native species’ that appears in the schedule 9 list under the Wildlife Countryside Act (1981) and it has been recognised as problematic for over 3 decades.

It is an offence under the Wildlife Countryside Act (1981) to ‘plant or otherwise cause to grow in the wild’ any plant listed in schedule 9, part 2, which includes Japanese Knotweed. Furthermore, since 2014, landowners (including private householders) who do not control Japanese Knotweed in their property can face prosecution. The value of a property may be significantly affected if Japanese Knotweed is present and when selling a property the owner is legally responsible to declare its presence or they may be liable for any costs incurred in dealing with the problem at a later date (including any legal costs). Therefore it is essential to seek professional advice from a reliable, experienced specialist that can provide suitable guidance through what can be a worrying situation.

What is Japanese Knotweed

There are several varieties of Japanese Knotweed in its natural habitat. They usually grow near roads, rivers, on sunny sides of hills, mountains and ditches, and are spread normally by seeds. Japanese Knotweed has strong rhizome systems which are the stems that grow parallel just beneath the ground; sometimes, rhizomes are mistakenly called roots. Rhizomes are like stems that grow underground and they can damage foundations and infiltrate structures. Japanese Knotweed rhizomes can grow down to a depth of three metres and extend outwards up to seven metres. Japanese Knotweed normally spreads via its rhizomes; a fragment as small as 0.7 grams of viable rhizome is enough to give rise to a new plant, information can be found with our Japanese Knotweed surveys. At the mature stage, the stems are hollow and not woody and can be snapped easily to show their hollowness.
