I would not hesitate to recommended the services of Knotweed (Japanese) Ltd. Our land was riddled with the stuff after a particularly lengthy summer; nothing our gardener attempted seemed to rid the infestation, but after an educational discussion with James, my mind was at ease and his men were on site within the week. Three months later and not a peep from those pesky weeds!
