Japanese Knotweed Specialist

When this invasive plant first arrived in the UK, its exotic appearance and striking red and purple flowers wowed Victorian botanists and found favour amongst horticulturalists. But as gardening trends changed, it became a fading fad and was dumped along roadsides, in quarries and in gardens, where it began to spread. From just a 2mm fragment of root, it can regrow and dominate shady corners and the inhospitable rocky ground of stream and river banks.

A number of physical and chemical methods have been proposed for Japanese knotweed control, with varying degrees of success. Various studies suggest that the most effective treatment approach is continuous cutting coupled with foliar herbicide application. However, these treatments are labour intensive and expensive. They can also exacerbate knotweed dispersal, as cutting stimulates growth by stimulating rhizome fragmentation.

The majority of research and management activities to date have focused on the use of glyphosate. However, there are many different formulations and other active ingredients promoted for the control of Japanese knotweed, but few have been rigorously tested at field relevant scales.

Mortgage lenders are increasingly requiring assurances that Japanese knotweed is fully managed before lending on properties with it present.
