Herbicide treatments involve spraying herbicide directly onto the foliage of the Japanese knotweed. Yearly applications of a herbicide treatment can control future growth.
An alternative to herbicide foliage spraying, stem injections involve injecting a concentrated dose of Glyphosate herbicide into each cane.
Sifting and screening is a method of removal that ensures all fragments and traces of knotweed are removed from the soil.
Japanese knotweed excavation solutions include: dig and dump, knotweed cap, on-site burial, dig and sift & on-site relocation.
A cost-effective method to halt the spread of Japanese knotweed – root barriers prevent the growth of roots, limiting their reach.
Controlled high-temperature Japanese knotweed incineration and removal from the affected site.
What Are the Long-Term Dangers of Japanese Knotweed?
While there are no impacts to human health, the damage to buildings, gardens and neighbouring land is vast, thanks to Japanese knotweed’s ability to spread up to 10cm a day in growing season. This invasive species will grow through concrete, tarmac and even building foundations.
Especially pressing for commercial developments where time and resources are finite and sensitive, project timescales can quickly come under costly jeopardy with a Japanese knotweed infestation. Conservation of the natural environment is also critical.
It's also illegal to let knotweed knowingly spread, and you could be fined or land a jail sentence in severe cases.
