Reminders issued on how to spot Japanese Knotweed, as more warnings are issued about invasive species

Homeowners have been issued with more new warnings about the dangers of Japanese Knotweed, NorthWalesLive has reported.

Described by the Environment Agency as “indisputably the UK’s most aggressive, destructive and invasive plant”, Japanese knotweed is notoriously difficult to treat.

It comes after NorthWalesLive revealed the worst place in Wales for the invasive plant – with nearly 400 infestations in just a four-kilometre radius.

The village in question – Capel Garmon near Betws-y-Coed – even contains enough of the aggressive species to make it into the top five worst places in England and Wales.

Warnings have been made by respected garden experts GardeningExpress – who reiterated how the weed’s root system and rapid growth can damage concrete foundations, buildings and roads.

They stressed that, as a result, some homeowners in the UK have even been unable to sell their homes because of evidence of knotweed on the property.

In fact, the plant is currently listed by the World Conservation Union as one of the world’s worst invasive species.
