Knotweed Risk in Shrewsbury

Japanese knotweed has been identified in the Shrewsbury area, covering postcodes SY1, SY2, SY3. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Shropshire has moderate knotweed risk concentrated along the Severn Valley through Shrewsbury and Ironbridge, and along the Shropshire Union Canal. The county's industrial cradle heritage in Ironbridge Gorge means some of the oldest established infestations in Britain. Telford's new-town construction imported contaminated soils to some sites.

  3. Contact a PCA-accredited company — Look for surveyors and treatment companies covering the SY1/SY2/SY3 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
