Japanese knotweed · Buckinghamshire

Japanese knotweed in Buckinghamshire

The Chiltern chalk streams, such as the Chess, the Misbourne and the Wye, and the Thames along the county's southern edge are places where invasive plants can spread along the banks. In gardens, knotweed is often found by boundaries and where garden waste or soil has been dumped in the past.

Knotweed is often spotted for the first time when a house is being sold or bought. If that is you, a free survey and, if needed, a formal CSJK (Certified Surveyor of Japanese Knotweed) survey report (£240, or £200 + VAT) can give your buyer, seller or lender the information they need. See our selling or buying a house page.

What to look out for

Knotweed dies back in winter, leaving brown, hollow canes, and comes back from the rhizomes in spring as red-purple shoots. If you are not sure whether you have knotweed or bamboo, read our bamboo or knotweed ID guide or send us a photo.

Excavation or treatment?

Some sites suit digging out, some suit herbicide or stem injection, and some need both. We recommend the right approach at the free survey. See treatment vs excavation.
