Japanese knotweed hotspots across Clydebank revealed by map

The data was gathered by Environet which estimates that around 5% of UK homes are impacted by this invasive plant species.

Discussing its interactive map, the specialist website said: "The Japanese Knotweed Heatmap is an interactive online heatmap of Japanese knotweed in the UK.

"Designed to inform homeowners and homebuyers of the local presence of knotweed and the potential risk to their property, the Japanese knotweed UK map is generated from over 57,000 known infestations, with new sightings added daily."

How to get rid of Japanese Knotweed

Here is how you can get rid of Japanese knotweed, according to the experts over at PriceYourJob.co.uk.

Plan Meticulously: Before diving in, assess the surrounding area. Are there nearby schools, playgrounds, or water sources that could be affected by herbicide overspray? Inform your neighbours about the treatment schedule to minimize exposure risks. Choose a late spring or early autumn window when the plant is actively growing.

Safety First: Don't underestimate the importance of proper safety gear. Wear overalls, a safety mask, gloves, and a face shield for protection. Sheets, tarpaulins, and rubble sacks will also come in handy.

Weather Matters: Choose a dry day with no rain forecast, as most herbicides can harm desired plants as well. Avoid windy conditions if using a spray application.

Targeted Application: A garden sprayer is effective for applying herbicide, but use caution near water sources or sensitive areas. Alternatively, a roller, cloth, sponge, or brush can be used for localized application. The herbicide should thoroughly cover the leaves and stems. For enhanced effectiveness, inject some herbicide directly into the stems near the base. Specialized tools are available for professionals, but a simple cut at the base followed by pouring herbicide into the opening can suffice.

Careful Disposal: Once cut, place all Knotweed material in sturdy plastic rubble sacks. You should contact West Dunbartonshire Council for more information on how to dispose of the plant remains.

Persistence is Key: Eradicating Japanese Knotweed is a long-term battle, not a quick fix. A single treatment won't do the trick. Be prepared to repeat the process 2-3 times a year for several years (3-5) until the weed is completely eradicated and shows no signs of regrowth.
