For reasons discussed in our DIY Japanese Knotweed Removal blog post, we DO NOT RECOMMEND attempting to get rid of Japanese knotweed on your own. Instead, get in touch with a specialist contractor who knows how to deal with this invasive species and ensure that it does not spread elsewhere.

How to kill Japanese knotweed

Broadly speaking, there are two ways to kill Japanese knotweed:

  • Herbicides - spraying the plant with weed killer

  • Excavation - digging the plant up and either burying it or safely disposing of it at an approved landfill site

We at Taylor Total Weed Control mostly use herbicides to kill Japanese knotweed. However, we can arrange excavation in special circumstances - this method is more costly, but it gets fairly quick results (whereas herbicides have to be applied repeatedly over a longer period).


What kills Japanese knotweed?

Japanese knotweed is a very resilient plant, and supermarket weed killers aren't always sufficient to destroy it. The Taylor Total Weed Control team use specialist herbicides to kill Japanese knotweed - these products are not available to the general public and can only be applied by qualified personnel.

Japanese knotweed is susceptible to a number of different chemicals, including glyphosates, picloram and triclopyr. When selecting a herbicide, it is enormously important to consider the effect that the chosen chemical(s) may have on the surrounding environment; for example, some weed killers are less selective than others and may damage neighbouring plants if not applied carefully.

It is also crucial to ensure that harmful chemicals are not allowed to contaminate any nearby water supplies.
