Get rid of invasive weeds at your property

Japanese Knotweed was first introduced in the 1850s and has since spread to occupy at least one site in every 10km2 across England and Wales. Japanese Knotweed identification is critical as this invasive plant can have a negative effect on property values. The 1981 Wildlife and Countryside Act makes it illegal to spread or to allow the spread of 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. Since Japanese Knotweed is now on the radar of mortgage lenders. Your mortgage application may be rejected if Japanese Knotweed is detected at or near the property boundaries and no treatment plan is in place. Unfortunately, the price of the house may seriously be devalued by a cash buyer. Japanese Knotweed has strong rhizome systems. Rhizomes are the stems that grow parallel just beneath the ground; sometimes, rhizomes are mistakenly called roots. They can potentially damage foundations, underground communications etc. Potentially this means that rhizomes look for weak places in structures, e.g. fractures or gaps to spread through. If the foundations and other structure are well built and there are no defects, there is no way for Japanese Knotweed to spread through and destroy. Fly tipping and ignorance are the biggest causes of this plant being spread unnecessary throughout the environment.

What are rhizomes?

Rhizomes are like stems that grow underground. 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.

Japanese knotweed stems

Japanese knotweed stems grow to 2-3 metres tall. They’re similar to bamboo with nodes and purple speckles and the leaves shoot out from the nodes in a zig zag pattern. The inside of the stem is hollow. At the mature stage, the stems are hollow and not woody and can be snapped easily to show their hollowness.
