Japanese Knotweed in Summer

Summer is finally here, and the sun has started to shine – bliss! You will have noticed that your gardens are flourishing due to the warm weather – but how do you know if you have Japanese Knotweed growing on your property?

Summer is probably one of the easiest times to spot Knotweed. In the early spring you would have seen red or purple shoots appearing through the ground, which would have turned into bamboo-like canes. By now, Japanese Knotweed will be fully grown and therefore easier to spot. The mature stems are hollow and have a distinctive purple speckle, with the leaves growing in a zig-zag pattern.

As we move into late summer, clusters of creamy white flowers will start to appear on the plant. These flowers are nectar rich, so you may identify the presence of Knotweed by noticing more insects in your garden.
