What Is Japanese Knotweed?

Japanese knotweed (Fallopia japonica) is a fast-growing perennial weed native to Japan. Believed to have been introduced to the UK in the Victorian era as an ornamental plant, Japanese knotweed has grown extensively and is now considered to be quite the problem plant.

One of the main reasons why Japanese knotweed is such a nuisance is the damage it can cause as it grows. While the plant can't break through a solid wall, it may exploit a structure's existing weaknesses, sometimes pushing through small cracks and gaps in brickwork, fences, pavements, etc. It can even grow inside pipes and disrupt underground cables.

These potential complications can make homes with Japanese knotweed difficult to sell, insure and mortgage. Knotweed spreading from one property to another has been at the root (no pun intended) of many legal disputes between neighbours.
