Due to its strong growth and the fact that its roots reach several meters into the ground, the knotweed can only be destroyed with great difficulty. Basically there are only two options:
- Destruction with a herbicide ("Roundup")
- radical cutting back of any new shoots
- Digging up the soil and removing all roots.
