Why is Knotweed a Problem?

  • Japanese knotweed is an invasive and resilient weed.
  • The rhizomes and roots extend deep into the ground and can re-emerge many years after treatment.
  • If left to grow and spread it has the potential to cause damage to the hard landscaping and buildings.
  • If the property is for sale the buyer’s mortgage lender will want evidence that there is a fully funded 10 Year Knotweed Management Plan (KMP) in place.

What is a Knotweed Management Plan (KMP)?

  • A Knotweed Survey is performed to identify the extent of the problem and assess the risks to the property.
  • A Treatment plan is drawn up that will control and eradicate the knotweed.
  • The treatment plan has a 10 Year Insurance Backed Guarantee.
