What Is Japanese Knotweed

Japanese knotweed, or Fallopia japonica, is a fast-growing, invasive plant species native to East Asia. It was introduced to Europe and North America during the 19th century as an ornamental plant and for erosion control.

Japanese knotweed is an invasive weed and is known for its bamboo-like appearance with hollow stems and large, green, spade-shaped leaves. It produces clusters of small, white flowers in late summer and early autumn. However, it is it’s growth habits that cause concern.

Japanese knotweed spreads aggressively through its extensive root system, or rhizomes, which can spread up to 7 meters horizontally and 3 meters deep. This rapid and robust plant growth, can cause damage to building structures, pavements, and drainage systems. It can also outcompete native plants, leading to a decrease in biodiversity. This is why its imperative you use a Japanese knotweed Specialist to identify and remove your knotweed problem.

Due to its destructive nature and the difficulty of fully eradicating it, Japanese knotweed is classified as an invasive species in several countries, including the UK and the US. It is illegal to allow this plant to spread in the UK as per the Wildlife and Countryside act, and management and removal must be carried out by Japanese Knotweed Specialists to ensure the plant is fully eradicated and does not return.
