Japanese knotweed has become a major problem on a lot of developments in the UK. Knotweed is a tall perennial plant which was introduced to in the early 1800's as an ornamental garden plant.

It grows at a rate of several metres a year and can cause structural damage especially to paths and tarmac. New shoots will push to the surface, even though the roots are buried one metre deep.

Eradication of Knotweed can only be achieved by total root removal for either off site or on site burial or intensive chemical treatment.

Acer carry out treatment of Japanese knotweed for a number of clients either as part of the landscaping package or a separate item.
