Identify Japanese Knotweed

Within this app are several ‘tools’ if you are worried that you might have a Japanese Knotweed infestation. Within the identify section are descriptions of the weed at various points of the year, along with close up images of what it looks like at these times.

And if you are worried that you might have an infestation that use the ‘Do I Have Japanese Knotweed’ button to get in touch with us. You can simply enter a few details so that we can contact you with our opinion, then using your device’s camera take a photo of the plant and email that to us. The form will also capture your GPS co-ordinates, which will give us more information about how likely it is that the plant is Japanese Knotweed.

Japanese Knotweed Facts

The plant can cause significant damage to construction work and has the power to grow through tarmac, paving stones, brickwork and cement.

Through cell expansion, the plant will find the smallest crack or joint and force its way through, cracking the already damaged material.

More facts


Because lenders will no longer release funds without proof of invasive plant eradication or a control management plan, early identification is essential. Japanese knotweed is a distinctive plant and it is important to recognise it to prevent further contamination.
