Japanese Knotweed and How to Remove Them

Polygonum cuspidatum or Japanese Knotweed is touted as one of the most invasive plants and this is why it is also sometimes known as Godzilla weed. As much havoc as the monster truly spreads, the weed also is extremely invasive and is a nightmare for most property owners. If you have ever tried to eradicate this noxious weed then you are well aware of the qualities it has. The weed is known to be so tenacious that it grows through solid masonry foundations. Here are the four top methods you can use to eradicate it from your property-


  • • Use of herbicide to kill them
  • • Smothering with tarps
  • • Cutting down to the ground
  • • Dig out the rhizomes


Glyphosate-based herbicides are the best ways to get rid of these. However, it is essential that you make repeat attempts at getting rid of them throughout the year. If you opt to cut it then make sure that during the summer you make it a habit to cut it regularly. It will ensure that they do not get the chance for photosynthesis and hence the growth will be reduced to a great extent. The most effective way is to use it all in mixture throughout the year because one process isn’t sufficient for these invasive weeds.
