Additionally, the plant can spread easily from fragmentation: even a small piece of stem or root can generate a new plant. Japanese knotweed is considered a serious pest in many countries, and efforts are underway to control its spread.
How do the roots of this weed spread so far and how deep do they go underground?
Japanese knotweed is a fast-growing, invasive weed that can cause serious damage to foundations, walls, and drainage systems.
The plant has an extensive root system that can spread up to 6 metres from the main stem, and the roots can grow up to 3 metres deep.

How far do Japanese knotweed roots spread underground?

One of the most notable features of Japanese knotweed is its extensive root system. The roots can spread up to 6 meters (20 feet) underground and can persist for many years after the plant has been removed.
What damage can they cause to infrastructure and foundations?
The plant’s roots can grow up to 3 feet long and penetrate deep into the ground, causing cracks in sidewalks, driveways, and buildings. As well as this it can clog up sewers and drain pipes causing issues of flooding and contamination too.
In addition, the plant’s rapid growth can quickly overwhelm garden beds and choke out native plants.
Japanese knotweed is a versatile plant that can find the smallest gaps and exploit them to ensure it has room to grow and spread out. From fissures to cracks, knotweed opens these up to cause much more significant damage over time if left unchecked.
Are there any long-term solutions to keeping this weed from spreading further into our ecosystems and landscapes?
