Japanese Knotweed Dos & Don’ts

Japanese Knotweed Do’s and Don’ts

  • Do understand that the presence of Japanese Knotweed will not prevent the sale of your home or the development of land if the problem is dealt with professionally.
  • Do be aware of the legal responsibilities surrounding Japanese Knotweed to protect yourself from future prosecution.
  • Do feel free to call us, Email us, or send through a photograph of any suspected growth to our WhatsApp Group.  We are always here to help.
  • Don’t try to treat the Japanese Knotweed  yourself as this could cause the infestation to further spread.
  • Don’t cut down Japanese Knotweed or mow or strim as this will cause the plant to further develop.  It is important to remember that all parts of the plant as classed as controlled waste and must be disposed of by a licensed waste carrier.
  • Don’t try to dig up Japanese Knotweed as this will lead to a significant increase in stem density. Even a small fragment of rhizome is capable of regeneration.
  • Don’t spread or move soil that is contaminated with Japanese Knotweed. Any soil that is within 7m of a Japanese Knotweed plant could contain rhizomes.
  • Don’t add Japanese Knotweed to compost.
  • Don’t take Japanese Knotweed to your local recycling centre that receives garden waste as it will contaminate the site and leave you liable for potential prosecution.
  • Don’t dump garden waste contaminated with Japanese Knotweed in the countryside.
  • Don’t break the law. Remember, if you cause Japanese Knotweed to spread you are guilty of an offence under the Wildlife and Countryside Act, 1981.  So, take care and deal with this invasive plant the correct way.
