Japanese knotweed is relatively easy to identify, once you know what the characteristics are. These include;
• Asparagus-like spears emerging in spring • Bright green shield shaped leaves that form a zig-zag shape on the stem • Tall green canes, with purple speckles • Clusters of creamy white flowers in late summer • Brown, brittle canes left standing in winter

If you are still unsure, we offer a Japanese knotweed identification service. Email your photos to firstname.lastname@example.org and we'll tell you if Japanese knotweed is present. If it is, then we will help guide you through the removal and treatment options.
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.
