Knotweed Risk in Dewsbury

Japanese knotweed has been identified in the Dewsbury area, covering postcodes WF12, WF13. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

West Yorkshire is a major knotweed hotspot. The Aire and Calder Navigation, Rochdale Canal, and Huddersfield Narrow Canal distribute the plant across Leeds, Bradford, Halifax, and Huddersfield. Former textile mill sites along virtually every river valley, combined with dense Victorian-era workers' housing and an extensive railway network, have created some of the highest infestation densities in northern England.

What to Do If You Find Knotweed in Dewsbury

  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 WF12/WF13 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
