Season of growth
During the spring months, Japanese knotweed begins to grow rapidly. This thick, invasive, and destructive plant grows between 10cm and 20cm a day with roots deep in the ground, making it difficult to remove.
The plant will keep on growing throughout summer before dying back towards the end of autumn.
