Knotweed Risk in Lincoln

Japanese knotweed has been identified in the Lincoln area, covering postcodes LN1, LN2, LN5, LN6. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Lincolnshire has low knotweed density. The county's flat, intensively farmed landscape, limited Victorian-era urban development, and well-drained soils make it less susceptible. Infestations are largely confined to Lincoln city, Grimsby's industrial areas, and along the few canal routes that cross the county.

What to Do If You Find Knotweed in Lincoln

  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 LN1/LN2/LN5/LN6 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
