| THis RHS page has plenty of informations about the legal niceties and also information about not confusing JK with other plants. However if you have what appears to be JK, and aren't prepared to wait years for a Court to finally decide in your favour having forked out thosands in legal costs in the meantimne or spend hundreds for contractors to use the strong stuff, you can try tackling it yourself with a glyphosate solution. Spring and summer are best time just be sure to keep it off everything else. Either paint it on the leaves or exposed cut stems rather than nspraying which should eventually kill it to the roots after one or two seasons. So the earlier the better https://www.rhs.org.uk/weeds/japanese-knotweed startquote For home gardeners, perhaps the most effective and simplest method to tackle Japanese knotweed is with a glyphosate-based weedkiller such as Roundup Stump Killer. This has label recommendation for controlling Japanese knotweed, instructing it to be applied to the cut canes or a foliar spray. Roundup Ultra also has label control for this weed Alternatively, try other tough formulations of glyphosate (e.g. Doff Weedout Extra Tough Concentrate or Westland Resolva Pro Xtra Tough oncentrate) Glyphosate-treated knotweed will often produce small-leaved, bushy regrowth 50-90cm (20in-3ft) in height the following spring. This is very different in appearance to the normal plant and it is essential that this regrowth is treated enquote: michael adams |
