Japanese Knotweed eradication

Japanese Knotweed is one of the hardest invasive plants to fully remove from your property. It’s fast growing ability means it can fully take control of your land if not treated early, leading to potential japanese knotweed damage to your property, a decrease in property value or costly legal battles if you have allowed knotweed to spread to a neighbouring property. Its complicated network of roots (rhizomes) make it especially difficult to remove, as most homeowners may not know how to get rid of Japanese Knotweed properly, simply removing the plant when they see it, not accounting for the roots that will lead to regrowth.

Japanese Knotweed’s robust plant structure means has the ability to grow in most environments. With it’s low temperature tolerance it can quickly exploit gaps in structures such as concrete and brick. By using an experienced knotweed removal specialist, with extensive knowledge of how to get rid of Japanese Knotweed, you can control the problem.
