Other Invasives


As well as helping clients deal with Japanese Knotweed, we also treat other invasive species and general nuisance weeds.


Below, you can find information on some of the invasive species that we can help you with.  If you have an overgrown garden area or green space surrounding your property, please feel free to get in touch.  We can assist with all of these problems.

We will keep adding more species to this list over time.
