Client Problem

A commercial client in Glasgow contacted JBB Knotweed Solutions after discovering a significant outbreak of Japanese Knotweed along the boundary of their sports complex. Aware of the legal obligations surrounding invasive weed control, they needed an effective management plan to prevent the spread of the weed to neighbouring properties. During our detailed site survey, we also identified the presence of Himalayan Balsam, another fast-spreading invasive plant.

Our Expert Solution

A full site survey conducted by our CSJK-certified invasive weed surveyors, mapping the full extent of the affected areas.
A 3-year herbicidal treatment plan, followed by 2 years of ongoing monitoring to ensure complete eradication and no regrowth.
Winter site visits to remove dead Japanese Knotweed canes, improving access for more effective treatment during the growing season.
Installation of on-site signage to reduce the risk of cross-contamination and disturbance during works.
Annual monitoring inspections to check for any regrowth and ensure long-term success.
Final site inspection and official sign-off upon completion of the programme.

Site Challenges and Solutions Delivered

Our initial site survey confirmed a large, mature stand of Japanese Knotweed, along with scattered patches of Himalayan Balsam across the site.
The client required a cost-effective invasive weed removal solution, delivered within a clear timeline to support planning for site re-use.
Treatments needed to be carried out outside of core school hours to minimise disruption and ensure safety for nearby users of the facility.
Unpredictable weather conditions across the three-year programme required careful scheduling and flexibility, ensuring all herbicidal treatments were applied at the most effective time for optimal results.

They were highly satisfied with the complete removal of both Japanese Knotweed and Himalayan Balsam, which allowed them to safely reopen the site and avoid any legal liabilities related to the spread of invasive plants.
