Question: Can you kill Japanese knotweed and if so how?
Answer: Japanese knotweed cannot be ‘killed’ as such – but it can be controlled over time and removed. The main methods for killing Japanese knotweed include herbicide treatments and excavation.
A Closer Look:
The primary methods for killing Japanese knotweed (Fallopia japonica) are herbicide treatments and excavation. Herbicide treatments involve multiple applications over several growing seasons to penetrate the plant’s extensive root system and prevent regrowth. This method is widely used due to its effectiveness in controlling the spread of knotweed over time.
Excavation is another effective method, involving the physical removal of the plant and its rhizomes from the soil. This approach provides immediate results but can be labour-intensive and costly.
