There are no other weeds as damaging and invasive as Japanese Knotweed. It can grow in almost all climatic conditions and it spreads to neighboring areas very fast. Once infested with this weed, It is extremely difficult to get rid of it. Even while removing it from one plot of land, care must be taken while disposing it of because new plants will grow from the stems and roots you have already removed. Improper disposal will help the weed to spread to other areas as well. There is practically no way to destroy its roots. The roots travel long distances and they can reach a depth of 3 meters. It is from these roots that new plants spring up. New plants also grow from the stems. If you cut one stem, you will find many more new shoots coming up from the place where you cut it. The growth of the weed is so fast that it becomes almost impossible to control it. Digging the soil is a means to remove the roots but it is not feasible to dig 3 meters deep just to remove a weed. Herbicides have not proved very effective against this weed. If allowed to grow, Japanese Knotweed can damage vegetable gardens and backyards of homes. The roots can reach the walls and basement of homes and crack them. Before a new house is built, it is necessary to remove the weed completely; otherwise the foundation of the new house will be weakened by the rhizome of this weed.
