Can penetrate through drains.

  • Hard surface property damage is the most common problem. Loose aggregates, patios & driveways can all be ruined; the rhizome can expand once established with enough force to cause destructive structural damage.


  • Underground rhizomes can penetrate through drains, sewers and foundations seeking a better water supply. It will find a way into a crack and just keep growing.


  • It is invasive and acutely impacts on our native flora and fauna biodiversity, creating large expansions of monoculture vegetation. Devaluing our natural landscape.


  • When Japanese Knotweed colonises riverbanks, it can damage flood defence structures and reduce the capacity of channels to carry flood water, increasing flooding risk.


  • When present on a property it can impede and in very serious cases prevent a property sale from completing.


  • If left to get established there can be huge costs associated with the removal and eradication of Knotweed from a site.


  • It can grow extremely densely and shades out native plants, which also provides poor habitats for insects, birds and mammals decreasing biodiversity.

Problems.

Japanese knotweed is able to colonise in a variety of urban and rural environments, so the problems caused by this plant can be far reaching.


The economic and social costs caused by the plant are huge and recently DEFRA estimated the cost of a national eradication programme to be in the region of £1.56 billion.
