What is Japanese Knotweed?

Japanese Knotweed is Britain’s most invasive non-native plant. Originally introduced in 1825 from Asia as an ornamental plant. Due to its highly invasive nature it has now escalated to highly concerning proportions soon taking over any areas it is allowed to develop.

Why is it such a problem?

Japanese Knotweed is actually an amazing plant, its vigour is quite remarkable growing in ideal conditions between 5 and 10 cms daily. Native species of plants don’t stand a chance here, being taken over without being able to compete. Japanese Knotweed has no natural enemies. Japanese Knotweed also, due to its incredibly aggressive growth will emphasise any weakness in foundations, road structures, car parks, walls etc., causing, in many cases, costly damage if not addressed quickly and professionally. Japanese Knotweed in the UK is now covered by a number of legal orders, namely Wildlife and Countryside Act 1981, Environment Protection Act 1990, Community Protection Notices.

Identifying Japanese Knotweed

    Spring

    In Spring the roots begin to emerge, these are very unique and identifiable but also hard to discover.

    Summer

    When the summer months arrive, the stems are longer and the plant will have grown significantly.

    Autumn

    Once the plant has reached a significant height it will bloom as shown in the image above.

    Winter

    During the Winter months, the stalks are a very strong and rigid form, this is the hardest to remove.
