Knotweed Risk in Leamington Spa

Japanese knotweed has been identified in the Leamington Spa area, covering postcodes CV31, CV32. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Warwickshire has moderate knotweed risk, particularly along the Grand Union and Oxford canal corridors and the Avon Valley. Proximity to Birmingham means contaminated soil movement is common. Former industrial sites in Nuneaton, Rugby, and the M6 corridor have established infestations, though rural areas in the south remain largely unaffected.

  3. Contact a PCA-accredited company — Look for surveyors and treatment companies covering the CV31/CV32 postcodes
