What is Japanese Knotweed?
Japanese Knotweed is a highly invasive plant which is extremely difficult to eradicate from land due to the fact that it spreads by its roots and stems, and can spread very rapidly. It can be known to grow as much as 10cm in a single day. Even if the smallest part of a root or stem is left behind when Japanese Knotweed is removed, it can reinfest the land.
What impact can it have on my property?
Due to its extensive roots, Japanese Knotweed can grow into the foundations of a building resulting in structural damage.
As a result, the presence of Japanese Knotweed at or nearby a property can impact the ability to obtain a mortgage over the property or finding an insurance policy. It can also put buyers and tenants off of proceeding with transactions, as well as reducing a property’s value.
Removing Japanese Knotweed
Japanese Knotweed is designated as a controlled waste by virtue of the Environmental Protection Act 1990. This means the waste can only be taken to an appropriately licenced waste facility and the removal should be carried out by an organisation with the proper licences.
The cost of treatment to remove Japanese Knotweed can be costly and often involves a series of treatments over time. If you become aware of Japanese Knotweed at your property, you should seek the assistance of a specialist and look for treatments that are backed by guarantees. When selling a property, you will usually be asked to disclose whether there has been Japanese Knotweed at the property.
