Yes. Japanese Knotweed across Cardiff is growing in numbers. This may be due to the heightened awareness of Japanese Knotweed with home buyers, sellers, and owners now very much more aware as are surveyors, banks and building societies and conveyancing solicitors.
After the Supreme Court Case in 2018 found Network Rail liable for Japanese Knotweed spreading from their land on to privately owned land, the Judge ordered Network Rail to pay the landowner compensation for devaluation of the property by the presence of Japanese Knotweed and ordered them to pay for a treatment plan and subsequent 10-year Insurance Backed Guarantee.
Japanese Knotweed can appear literally anywhere throughout Cardiff and there is no place that the dreaded weed seems to not be able to grow.
