THE BEGINNING OF THE END
With the nights drawing in and a definite autumnal feel to the weather, you will be seeing the change in unmanaged Japanese Knotweed. The white flowers will be starting to shed and you will see the outer and lower leaf’s starting to yellow or brown as the chlorophyll starts to disappear from the leaf. Its an interesting process which we will follow up on soon.
As the leaf dies the nutrients are drawn from the above ground vegetation back down into the roots where they are stored and used during the winter months to keep the roots / rhizomes alive.
This process is why a late autumn application of herbicide can be so effective in the management of Japanese Knotweed. The herbicide is drawn deep into the root network where it can cause the most damage to the rhizomes when this perennial is at its most vulnerable.
