Knotweed Risk in Milton Keynes

Japanese knotweed has been identified in the Milton Keynes area, covering postcodes MK1, MK2, MK3, MK4, MK5, MK6, MK7, MK8, MK9, MK10, MK11, MK12, MK13, MK14, MK15. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

Buckinghamshire has low to moderate risk, with knotweed found along the Grand Union Canal through Aylesbury and the Chiltern railway corridor. Milton Keynes' extensive new-town construction imported contaminated topsoil to some sites. The county's chalk soils in the Chilterns are less hospitable to knotweed than the clay vales.

What to Do If You Find Knotweed in Milton Keynes

  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 MK1/MK2/MK3/MK4/MK5/MK6/MK7/MK8/MK9/MK10/MK11/MK12/MK13/MK14/MK15 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
