Knotweed Risk in Crewe

Japanese knotweed has been identified in the Crewe area, covering postcodes CW1, CW2. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Cheshire has moderate knotweed risk focused along the Shropshire Union Canal, Trent and Mersey Canal, and the Weaver Navigation. Chester's Roman and Victorian heritage gardens harbour old infestations, and the Mersey corridor through Warrington carries the plant from Manchester. Salt industry subsidence sites in Northwich and Middlewich have created disturbed ground suitable for colonisation.

What to Do If You Find Knotweed in Crewe

  1. Do not disturb the plant — Cutting, strimming, or digging spreads rhizome fragments and makes the problem worse

  3. Contact a PCA-accredited company — Look for surveyors and treatment companies covering the CW1/CW2 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
