Japanese knotweed identification in winter

In spring and summer months, Japanese knotweed is relatively easy to identify once you know what the characteristics are. Surveyors are expected to identify knotweed throughout all the seasons, even though in winter this problem weed becomes trickier to spot. Things to look out for are; 

• Brown, brittle canes left standing • Distinctive crowns in the ground •  Scorched areas of grass and bare patches of earth •  Smaller plants with distinctive zig zag stem distribution

A growing number of surveyors are being sued for professional negligence as a result of missing Japanese knotweed during surveys. We're here to help make sure knotweed can be correctly identified whatever the time of year.

Take a look at the images below. You can also visit our picture gallery and watch our 3 minute video on How to identify Japanese knotweed. We've also produced a Japanese knotweed Identification Guide, which you can download to help you identify the plant in situ.






If you are unsure, we offer a Japanese knotweed identification service. Email your photos to expert@environetuk.com and we'll tell you if Japanese knotweed is present.

This is a free service. However, if you would like to make a small donation to a worthy charity via JustGiving that would be appreciated.
