The Facts on Japanese Knotweed

Date: October 2, 2015

Fallopia Japonica also know as Japanese Knotweed was introduced to Britain from Japan in 1825 as an ornamental plant however it is now illegal to let the plant stray from your land onto others therefore extra care needs to be taken.

The plant typically grows to height of 2 metres in spring/summer with the shovel-shaped leaves growing up to 14cm in length.  The plant produces white flower tassels in the late summer/early autumn which can reach up to 15cm in length.

Due to its wide-ranging root system, which can extend up to 3m in dept and 7m in all directions, Japanese Knotweed can cause serious damage to buildings, drains and construction sites if left untreated.
