Himalayan knotweed as bad as Japanese knotweed?
I have recently discovered quite substantial stands of Himalayan knotweed near to the river Blackwater, along the way I discovered a house which is obviously inhabited by a builder of some sort and had recently done some building work of their own...I wonder do they realise what this plant is poking up from their building soil?!?! I found out that the house a mere 200 m downstream was the son to this household and guess what was in his back yard too! Classic example of spreading through top soil. Can anyone tell me if Himalayan knotweed presents the same danger to building work as Japanese knotweed???
