Does Cutting back Japanese knotweed stimulate growth rather than controlling it.

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.
