Knotweed Risk in Totnes

Japanese knotweed has been identified in the Totnes area, covering postcodes TQ9. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Devon's warm, damp climate and extensive river valleys make it highly susceptible to knotweed colonisation. The plant thrives along the Exe, Dart, and Taw river corridors and was a popular ornamental in Victorian and Edwardian gardens throughout the county. Railway embankments connecting Exeter, Plymouth, and Barnstaple have accelerated spread.

What to Do If You Find Knotweed in Totnes

  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 TQ9 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
