Japanese knotweed is an invasive plant species[2023]
There are no known specific herbivores that feed exclusively on Japanese knotweed, insects and animals may consume small amounts of the plant as part of their diet. Control of Japanese knotweed requires a multi-faceted approach including physical, chemical and biological methods.
Does Cutting back Japanese knotweed stimulate growth rather than controlling it.
When the plant is cut, the stem and leaves will die back.But the rhizomes (underground stem) will remain alive and will send up new shoots. This can lead to the infestation becoming more widespread.
It’s generally recommended to use other methods to control Japanese knotweed such as digging up the roots, using herbicides These methods aim to target the roots, which is the most effective way to control the plant.
It’s always best to consult with an expert in order

For example, the larvae of the knotweed stem borer moth (Achlya flavicornis) feed on the stem and leaves of the plant But they do not cause significant damage to it. Similarly, deer and rabbits may browse on young knotweed shoots, but they do not control its spread.
Japanese knotweed is a highly resilient and adaptable plant species that is difficult to control or eradicate. Its deep roots and underground rhizomes allow it to regenerate quickly after being cut down or treated with herbicides. Therefore, it is not a preferred food source for any species.
In most cases,
the control of Japanese knotweed requires a multi-faceted approach that includes a combination of physical, chemical, and biological methods. This includes manually digging up the roots. Applying herbicides, and using biocontrol methods such as the release of insects that feed on the plant. in summery the answer to Does cutting back knotweed stimulate growth is yes.
