Over 4000m² of long‑established Japanese Knotweed treated at a South London retirement home. IVM delivered a full seasonal programme using the IVM FAST System, supported by monthly reporting and guaranteed site clearance.
Retirement Home – Severe Knotweed Infestation
A retirement home in South London was affected by a large, long‑established Japanese Knotweed infestation covering over 4000m². The growth was spreading toward landscaped gardens and the main buildings, and all previous treatment attempts had failed. Our PCA‑accredited Japanese Knotweed specialists were instructed to provide a reliable, long‑term remediation plan tailored to the site.
Project Overview
Location: South London
Site Type: Retirement Home
Planning Status: N/A
Contamination: 4000m²+ of established Japanese Knotweed
Risk: Spread toward gardens and main buildings
South London presents unique challenges for Japanese Knotweed remediation due to dense residential layouts, older boundary structures and limited access routes. IVM regularly supports clients across South London, including Croydon, Bromley, Sutton, Lambeth and Merton, delivering guaranteed Knotweed solutions for both residential and commercial sites.
The Challenge
The site had a long history of unsuccessful treatment attempts. The infestation was extensive and advancing toward high‑use areas, requiring a structured remediation strategy delivered by our commercial Knotweed removal team and supported by clear documentation for property managers and stakeholders.
Our Solution – IVM FAST System
IVM implemented the proprietary
IVM FAST System,
beginning with the first herbicide treatment in late May. Site visits and treatments continued throughout the growing season,
supported by monthly Site Progress Reports to keep the client fully informed.
By December, the site was fully cleared and guaranteed, providing long‑term protection and peace of mind for the property managers.
Outcome
• Complete eradication of Japanese Knotweed
• Guaranteed long‑term protection
• Structured treatment programme with monthly reporting
• Successful remediation following previous failed attempts
