Do you treat Japanese knotweed?
Our Estate Services team will treat Japanese knotweed.
We will carry out an inspection first, and upon confirmation of the Japanese knotweed we will treat within the site where the Japanese knotweed is located.
Rather than spray the knotweed three or four times per year, as is commonly suggested, we have had more successful results by treating the knotweed just once in the growing season. This is because the knotweed has a larger leaf area to absorb the chemical and is also drawing nutrients, so the herbicide that we apply will go down into its root structure before it dies back for the winter. This technique has given excellent results and our team will continue to monitor and treat any regrowth that may occur.
