What is Japanese Knotweed?

Japanese knotweed (Fallopia japonica) is a non-native invasive species of plant. Since it was introduced into the UK as an ornamental garden plant in the mid-nineteenth century it has spread across the UK, particularly along watercourses, transport routes and infested waste areas.

The plant can grow up three metres in one growing season, usually April to September. The stems are similar to bamboo and form dense thickets that persist when dead long in to winter. The plant has small white flowers that bloom in late summer and produce small triangular seeds that are dark brown in colour. The extensive underground rhizomes produce the new shoots the following spring, this is the main reason why Japanese Knotweed spreads, and as such, any soil that is contaminated with its rhizomes must be disposed of appropriately and is an offence under the Wildlife and Countryside Act 1981 to not to do so.

The Problems Japanese Knotweed Causes?

Specific problems caused by Japanese knotweed are:

Damage to paving and tarmac areas

Damage to flood defence structures

Damage to archaeological sites

Reduction of biodiversity through out-shading native vegetation

Restriction of access to riverbanks for anglers, bank inspection and amenity use

Reduction in land values

Increased risk of flooding through dead stems washed into river and stream channels

Increased risk of soil erosion and bank instability following removal of established stands in riparian areas

Accumulation of litter in well established stands

Aesthetically displeasing

Expensive to treat
