As part of our Japanese knotweed treatment, we use a glyphosate-based spray. While this is used in a stronger concentration than it might be for common gardening, there are highly unlikely to be any side effects to your pets.
Japanese knotweed can grow wherever there is a crack or a weak spot in your building. This voracious plant is able to grow up to 10cm a day. This means that the damage caused can be sudden and severe, as well as taking a lot of time and money to repair.
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.
