There are several different methods of treating Japanese knotweed. For most residential properties, we would recommend a herbicidal treatment over the growing season, followed by a period of inspection visits.
Japanese knotweed is quite a distinctive plant; but it does share many features with other similar weeds. For this reason, we would always recommend that a PCA certified surveyor visits your property to confirm whether or not the suspected plant is Japanese knotweed.
Japanese knotweed is commonly treated with a herbicide programme. This is conducted over several years and visits, to ensure that the knotweed is fully treated and does not re-emerge after a dormant period.
Japanese knotweed was brought to the UK back in the Victorian era and since then, it has spread across the entire nation. Due to Britain’s extensive canal and rail network, the knotweed has spread continuously, and is still doing so today.
