Treating Japanese Knotweed in Hampshire

Japanese knotweed is a highly invasive, aggressive plant found all over the UK, including the county of Hampshire. This invasive weed is detrimental to buildings and countryside across the Hampshire area, from Basingstoke to Southampton.

Why is Japanese Knotweed Such an Issue in Hampshire?

Hampshire, known for both beautiful rural areas such as Hartley Wintney and busy cities such as Winchester, can be a hive for the growth of Japanese knotweed. With one rhizome boasting the ability to spread up to 7m underground, and the plant itself growing 2cm a day, Japanese knotweed can do vast amounts of damage when left without treatment, breaking through garden walls and even crack or block drains.

Japanese Knotweed Removal in Hampshire FAQs

Am I legally obligated to remove Japanese knotweed from my property in Hampshire?

According to the Wildlife and Countryside Act 1981, it is an offence to plant or allow Japanese knotweed to spread. You may not be legally obligated to remove Japanese knotweed from your Hampshire property, but failure to prevent it from spreading may cost you £5,000 or even a prison sentence.

I’ve found Japanese knotweed on my Hampshire property – will it devalue it?

The value and success of selling your property with Japanese knotweed present will have varying results depending on the lender. Some may even reject mortgage applications. A surveyor’s report, however, will provide an accurate risk assessment to satisfy some lenders.

How much will Japanese knotweed removal cost for my Hampshire property?

The price of Japanese knotweed removal will vary depending on several elements, including:

  • Size of infestation  
  • Survey results
  • Method needed
  • Ecological state of the site

By considering these elements, amongst others, our experts can assess what is needed for the best price.

What insurance-backed guarantees are available?

Japanese knotweed can be extremely challenging to remove, and despite best practices, it can return. If just 0.2g of the Japanese knotweed rhizome is left behind, it can continue to grow at rapid speeds. That’s why here at Japanese Knotweed Specialists, we can arrange third-party insurance-backed guarantees to ensure you’re always protected. Our insurance-backed guarantees cover:

  • 5-year insurance-backed guarantees
  • 10-year insurance-backed guarantees
