Japanese knotweed in Sussex

In Sussex, knotweed is found in gardens, on waste ground and along watercourses such as the Arun, the Adur, the Ouse and the Rother, where fragments can travel downstream and start new stands.

If you are selling a home in Sussex, knotweed on the property or next to the boundary will come up on the TA6 Property Information Form. A professional survey, a management plan and a guarantee give buyers and lenders the evidence they ask for. See our selling or buying a house page.

What to look out for

If the knotweed is on, or right next to, a protected site such as a Site of Special Scientific Interest (SSSI), Natural England's consent may be needed before work starts. We check what applies to your site when we survey.

Excavation or treatment?

Some sites suit digging out, some suit herbicide or stem injection, and some need both. We recommend the right approach at the free survey. See treatment vs excavation.
