What to Do If You Find Knotweed in City of Aberdeen

If you discover or suspect Japanese knotweed on a property in City of Aberdeen:

  1. Don't disturb it — Cutting, mowing, or digging can fragment rhizomes and worsen the infestation

  3. Start treatment promptly — Early intervention limits spread and reduces long-term costs
  4. Obtain an insurance-backed guarantee — Essential for property transactions and mortgage applications
  5. Know your legal obligations — You must prevent knotweed from spreading to neighbouring properties
