The most economical Japanese Knotweed removal method is via herbicidal stem injections, this takes between 24 and 48 months, since two to four growing seasons are required to ensure that Japanese Knotweed is thoroughly eradicated.
In most cases, a herbicide treatment is the cheapest, easiest solution. However, if the land in question is to be used for redevelopment in the future, then excavation will most likely be required.
