JAPANESE KNOTWEED REMOVAL
In the nineteenth century, Japanese Knotweed looked like the ideal imported plant to help stabilise the embankments of Britain’s ever growing railway network. Thanks to its natural resilience, it could easily grow in the harshest of environments, and it looked nice as well.
Since then, it has continued to spread across the country causing destruction and unhappiness in residential and commercial gardens in Cardiff, South Wales and the rest of the UK. Its fast-growing robust roots are able to crack tarmac, undermine foundations and even invade homes.
In 2012, the Environmental Protection Agency launched an app to help track invasive plants and hopefully limit their spread. Since then, PlantTracker has been downloaded over 20,000 times, and more than 6,000 knotweed locations have been identified. You can download the PlantTracker app for iPhones on the Apple Store and for Android on Google Play Store.
So far PlantTracker results have shown that there is a heavy concentration of Japanese Knotweed in South Wales, particularly around Cardiff, as well as in the Midlands, London, and in Cornwall, where the plant was first introduced into ornamental gardens by the Victorians.
You can see the identified areas of Japanese Knotweed both in Cardiff and all across the UK with the PlantTracker Map.
We worked together with a housing association in Cardiff after they discovered a suspected infestation of Japanese Knotweed on some of their land. After we had identified the Japanese Knotweed, it was necessary to perform an excavation to remove it thoroughly.
We excavated and removed the Japanese Knotweed from three gardens in Cardiff which were due to be landscaped. The knotweed was taken off site and disposed of according to British standards.
After this, we installed vertical root barriers to prevent any potential reinfestation and also treated a neighbouring property with herbicide over a five-year period. The total cost of this treatment was £7000.
