Knotweed Risk in Burnley

Japanese knotweed has been identified in the Burnley area, covering postcodes BB10, BB11, BB12. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Lancashire has moderate to high knotweed risk due to the Leeds and Liverpool Canal, the Lancaster Canal, and former cotton mill towns in East Lancashire. River valleys including the Ribble, Calder, and Lune carry infestations through Preston, Blackburn, and Burnley. Victorian industrial housing and derelict mill sites provide ideal colonisation habitat.

What to Do If You Find Knotweed in Burnley

  1. Do not disturb the plant — Cutting, strimming, or digging spreads rhizome fragments and makes the problem worse
  2. Take photographs — From multiple angles, including close-ups of leaves and stems. Many treatment companies offer free identification from photos
  3. Contact a PCA-accredited company — Look for surveyors and treatment companies covering the BB10/BB11/BB12 postcodes
  4. Get a professional survey — This provides the RICS categorisation needed for property transactions and mortgage applications
  5. Start treatment — Early intervention is cheaper and more effective than waiting
