Japanese Knotweed removal in Redbridge is a growing problem, due to the unlawful disposal of the plant in several areas. In November 2016, bin bags of rubbish and Japanese Knotweed were found behind a Lidl store. The Japanese Knotweed was disposed of illegally, and whilst the visible signs of Japanese Knotweed were removed from the property, the rhizomes would still have been present in the soil, and therefore grow-back would have been expected. What is the most effective method of treatment to fully eradicate the invasive weed?

Japanese Knotweed is resistant to standard weed killer, and the translocating herbicide we use is significantly stronger than what is available to the public. For most domestic cases, we would recommend that spraying and injection of the plant be carried out, as it is the most cost-effective and comprehensive way to eradicate the weed. This is due to the dual application method, as well as 2 years’ worth of inspections of the affected area once the treatments have been completed.
