The Isle of Wight has been named as the worst location in the South East for Japanese Knotweed.

According to figures published by Environet UK, Shanklin tops the list with 84 infestations within 4 kilometres of the town.

Japanese Knotweed

The plant has been described by the Environment Agency as “aggressive, destructive and invasive”.

It grows rampantly along railways, waterways, in parks and gardens and is notoriously difficult to treat without professional help.

Second on the list is Reading in Berkshire and Tunbridge Wells in Kent.

Nic Seal, Founder and MD of Environet, said,

“Japanese knotweed has become a major problem in parts of the South East including much of Surrey, Kent and coastal areas of Sussex, impacting property prices, halting sales and causing a huge amount of stress and worry for homeowners.”

Environet has collected data from its online heatmap Exposed: The Japanese Knotweed Heatmap, which launched earlier this year.

It estimates that Japanese Knotweed currently affects 4% to 5% of UK properties, wiping a total of £20 billion off house prices.
