Japanese knotweed in the winter - dead canes

Japanese knotweed growing season ends as winter approaches

It is that time of year again when Japanese knotweed is dying away ready to spread its damage again in the spring.

Although still standing the bamboo-like canes will soon be brown, brittle and inert eventually decomposing over time. However, the rhizome system beneath the ground is still very much alive, waiting to emerge, bigger and stronger, with new shoots next March and April.
