Knotweed Risk in Canterbury

Japanese knotweed has been identified in the Canterbury area, covering postcodes CT1, CT2. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Kent has moderate knotweed risk, concentrated along the Medway Valley, railway corridors connecting London to the Channel ports, and the Thames estuary. Former industrial land around Chatham Dockyard and Dartford has established infestations. The county's extensive rail network, including HS1, has inadvertently spread rhizome fragments through track maintenance.

What to Do If You Find Knotweed in Canterbury

  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 CT1/CT2 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
