DIY Japanese Knotweed removal using herbicide treatment

Herbicidal treatments are an effective way of removing Japanese Knotweed from areas that are not ecologically sensitive. It is important to be aware of this before carrying out DIY Japanese Knotweed removal. In more sensitive areas, stem injection methods can be used; injecting the herbicide directly is less risky to the environment and to neighbouring plants, and is particularly useful when eradicating plants near water.

Once the herbicide has been applied and absorbed down to the rhizome, the weed cannot regrow. However, herbicide treatments can take up to 24 months to complete. Which may be extremely inconvenient when time is of the essence.

While removing Japanese Knotweed yourself is possible, it can be difficult, and if you don’t remove every last trace, it can grow back and spread even further. For this reason, we suggest contacting a professional Japanese Knotweed removal company, instead of opting for DIY Japanese Knotweed removal.

Dangers of Japanese Knotweed

Japanese Knotweed is one of the world’s worst invasive plant species (as classified by the World Conservation Union). And while not harmful to humans, its potential for damage comes from its invasive roots and fast growth rate. In ideal circumstances, Japanese Knotweed can grow up to 10cm a day, and as it spreads it can damage hard surfaces, like concrete, tarmac, and brick walls.

Japanese Knotweed is a voracious plant and needs to be identified and removed as quickly as possible to prevent further growth and damage. It is a criminal offence to let Japanese Knotweed spread to neighbouring properties, and if left untreated, it will spread quickly, causing costly damage as it goes. The urgency of removing this invasive weed makes opting for DIY Japanese Knotweed treatment incredibly risky when compared to enlisting in professionals.
