Japanese Knotweed Solutions

For gardeners seeking japanese knotweed solutions, using a variety of eradication methods from the outset will increase your chances of completely removing this invasive species. For example, covering the site in question with tarps during the growing season can suppress Japanese knotweed’s growth and ultimately kill it. Alternatively, digging out as much of the plant’s rhizomes as possible in autumn and early spring can also be effective.

However, be aware that it can take a few seasons to kill Japanese knotweed permanently using this method and it’s important to stick with the project so that no new rhizomes can sprout. It’s also worth noting that under the Environmental Protection Act 1990, rhizomes are classed as controlled waste and must be added to a licensed landfill site.

Exploring Japanese Knotweed Solutions: Effective Strategies for Control

A specialized geo-textile membrane can also be used to contain and control an infestation of Japanese knotweed, preventing it from spreading further. This can be especially useful where Japanese knotweed has spread through cracks in a house foundation or along paved surfaces.

A British start-up company has developed a device which promises to boil the roots of the weed, effectively killing it, without resorting to damaging herbicides. The RootWave machine works by directing 5kv of power to the plant’s rhizomes to ‘zap’ them. While it’s not yet available to the general public, it has already been trialled by Transport for London and is hoped that it will offer a safe and non-toxic alternative to traditional weedkillers.
