Control of Japanese Knotweed
Japanese knotweed, otherwise known as Fallopia Japonica, is a highly invasive weed that was introduced to Britain as an ornamental plant in the 19th century. Since then, it has gone on to inhabit many parts of the UK, causing problems for many homeowners/landowners with its robust growth. Japanese knotweed is capable of spreading across waterways, transport routes and waste grounds; even tarmac and concrete is vulnerable to its growth. All it takes is one small crack or weakness in the foundations or surrounding walls of a house for the plant to exploit it and severely damage the building’s structure.
Japanese knotweed also threatens native plant and animal life by forming dense networks of underground growth. The plant has the ability to adapt to its micro climate which can inhibit other plant growth, causing any flora in the area to wither and die. With roots reaching up to 3m deep, it can also block routes taken by wildlife and damage flood defence structures.
