Japanese Knotweed

Japanese Knotweed: Also known as Japanese bamboo due to the appearance of its stems.

A tall perennial plant it can grow up to 2-3m in height with leaves arranged in a zig-zag pattern on the stems, small white flowers appear between July and October. It’s another invasive non-native plant and regularly makes headlines due to its fast growth and ability to grow through weaknesses in concrete and asphalt. Control of Japanese knotweed is more difficult than some of the other species, as knotweed can regenerate through very small pieces of pieces of cut root or stem so strimmers should never be used around knotweed.

Chemical control is best carried out by a qualified contractor. Advice on selecting a contractor and other useful information can be found here: Controlling Knotweed

A key part of the strategy to control invasive plants is to know where they are, you can report sightings of Japanese Knotweed in the park here: https://record.bis.org.uk/.
