Japanese knotweed and construction sites – herbicide treatment or physical removal?

It’s a question we’re often asked, and there is a very clear answer. 

If your planned works are likely to result in ground disturbance do NOT rely on herbicide alone. The entire rhizome system should be removed, because the chances are that not all of the rhizome system will be killed by herbicide, the consequence being that your groundworks will spread the knotweed around the site, and possibly off-site too.

5 key facts Estate Agents should know about Japanese knotweed

Finding Japanese knotweed on a property can halt a house sale.

Whilst there are various ways to get rid of this invasive perennial, if identification is left until the 11th hour of the sale, it can become a nightmare problem to deal with. There’s a legal duty on Estate Agents to disclose the presence of Japanese knotweed under CPR, so in our experience it’s best to be honest with the buyer to gain their trust which should make any transaction go through without a hitch.

Does Japanese knotweed have any redeeming qualities?

Japanese knotweed (Fallopia Japonica), has earned itself a negative reputation in the UK.

Japanese knotweed is regarded as being the UK’s most aggressive and destructive plant, spreading across the UK and causing havoc to those unfortunate enough to own property in its way.  It’s undoubtedly a nuisance to have on your land. It causes damage to property, it's expensive to get rid of, and can potentially devalue your property.
