What is Japanese knotweed and why is it a problem?

Japanese knotweed is a fast-growing, non-native plant that can cause serious damage to property by exploiting weaknesses in foundations, drainage, and paving. It's notoriously difficult to eradicate and can significantly devalue a property.

Is it illegal to have Japanese knotweed on my property?

It is not illegal to have Japanese knotweed on your land, but it is illegal to cause it to spread into the wild or onto neighbouring land. You have a legal responsibility to control it and dispose of contaminated soil properly.

How long does Japanese knotweed treatment take?

Eradication programmes for Japanese knotweed typically involve multiple treatments over several growing seasons, usually 3-5 years, due to its robust underground root system. Guarantees are often offered for successful treatment.

Can I treat invasive weeds myself?

While some general weed killers might suppress invasive weeds, professional treatment is highly recommended for species like Japanese knotweed. Specialists have access to stronger, more effective herbicides and specific techniques, offering guarantees that DIY methods cannot match.
