Japanese Knotweed what is it

Japanese Knotweed – What is It?

Japanese knotweed is an invasive and resilient plant that can cause a great deal of damage to your property, if left untreated.

Japanese knotweed can grow to 3-4m in just 10 weeks.  Underground, its roots can spread 7m horizontally.

If there are gaps in between slabs or cracks in concrete, knotweed can grow into these gaps, meaning it has the potential to damage fences and outbuildings.

Knotweed cases have surged by a whopping 28 percent in the UK in the last five years, with 10 counties across the UK experiencing the largest growth.

Over the last five years, South Yorkshire has seen the most confirmed live cases with a more than 77 percent increase in the past five years.

South Yorkshire was followed by Hampshire, West Sussex, Kent and Powys.

In the last five years, the national average of confirmed cases has soared to a 27.91 percent increase. – Source – Article in express.co.uk

Is your property affected by Japanese knotweed?

If Japanese knotweed has spread onto your property from neighbouring land as a result of a failure to control the knotweed, you could be entitled to make a claim.

The owner of the neighbouring property could be responsible for paying to remove the knotweed from your land and theirs.

If the presence of the Japanese knotweed has reduced the value of your property, you may also be entitled to make a claim for the diminution in value.

Buying a new property/house?

If you are looking to buy a property, you need to instruct a surveyor to check for it.

Homes located close to railway tracks could be more at risk to be infected of Japanese knotweed.
