Japanese knotweed is a plant originating from eastern Asia (Japan, China and Korea). It is a highly invasive weed and has been described by the Environment Agency as “indisputably the UK’s most aggressive, destructive and invasive plant”. It was first introduced to the UK environment in the early 1800’s as an ornamental plant and to aid in stabilising the embankments.

The havoc that the knotweed can cause is so extensive that just the mere sighting of it in a property that is about to be sold can make the buyer withdraw from the transaction.

The plant can cause damage to things like concrete foundations, buildings, flood defences, roads, paving, retaining walls and architectural sites and it can also reduce the capacity of channels in flood defences to carry water.

Mortgage lenders will not offer mortgages or loans if their valuer sights japanese knotweed within close vicinity of a property.

To remove the knotweed from a property can be quite time consuming and extremely expensive, and even after all the problems with removing it, if the waste is not disposed of properly is a criminal offence as the plant is classified as Controlled Waste under the Environmental Protection Act 1990. It is also an offence to let this plant grow.
