Control Methods

Japanese knotweed is not treated by any normal means. Instead, it needs a special treatment by using a particular approved commercial herbicide chemicals. It involves using specific application techniques.

    • This involves a visit to your property to assess your infestation. We will discuss potential treatment plans with the best possible way to move forward.
  • Develop a Treatment Plan
    • Our experienced team will decide the best treatment plan that will get rid of your infestation that is cost effective. 
  • Stem Injection/Spraying
    • Our qualified professionals will target Japanese Knotweed at a certain point in its life cycle, optimising the effects of the treatment.
  • Dig/Remove
    • In order to get rid of infestations removal of the topsoil layer may be required to remove complex rhizome root systems. As soon as Japanese knotweed is removed it becomes non-hazardous waste.
  • Cell Membrane
    • Laying down a cell membrane prevents the spread of those complex rhizome root systems that makes the spread of Japanese Knotweed so rapid.
  • Monitoring
    • As Japanese Knotweed can take a few seasons to destroy, we will continue to monitor the effects of the treatment on your infestation.
