Identifying Japanese Knotweed
If you’ve never come across it, Japanese knotweed can be difficult to identify. The moment that many of our clients find they have a problem is when someone points it out to them.
It’s actually a fairly distinctive plant. You’ll notice green and purple canes that grow as high as 3 metres and, in the late summer, the plant has small white flowers. You might think that you can simply dig the knotweed up and get rid of it once you identify it.
The problem with Japanese knotweed eradication, however, is that the roots drill quite deep down into the soil. That means getting it all out can be difficult. If you leave just a few roots behind, the infestation will begin to flourish again.

Why Japanese Knotweed is Such a Problem
The invasive nature of the knotweed will soon becomes apparent once it has been identified. When disturbed, the plant can grow very quickly and its roots spread extensively. One of the main problems is that these roots can get into weak spots or cracks in your building foundations causing damage. Once the advanced network of roots develop, they can spread to adjoining properties, opening you up to a potential lawsuit if you haven’t done something to control the plant.
Frequently Asked Questions
As you might expect, Japanese knotweed eradication is actually a specialised service. Yes, you can try to do it yourself but don’t be surprised if the weed appears again pretty quickly after you think you’ve got rid of it. It can be backbreaking work to try and dig up all the roots and, depending on the ground, is often all but impossible without using some form of expert treatment.
Over the last 20 or so years, our team at Environet has developed a range of different tools for Japanese knotweed eradication. That includes our cutting edge Eco-Innovative Xtract™ which is an excavation and screening tool that is used to identify and remove the rhizomes of the plant in commercial properties.
If you don’t want to use herbicides, this process is a great choice. The good news is that it’s cheaper than many of the traditional approaches, diverts a lot of waste from landfill and works well for business locations including industrial estates.
Residential areas often need highly specialist approaches when it comes to Japanese knotweed eradication, mainly because buildings and gardens are smaller and closer together. At Environet, we use a couple of different trademarked approaches including DART™ and Resi-Dig-Out™ (a kind of scaled down version of our more commercial Eco-Innovative Xtract™).
Our treatments for Japanese knotweed eradication have been developed over many years, using the latest technology and our own experience. Of course, our specialists need to take a closer look at your property and the extent of the infestation before they decide which approach is best. The aim is to make sure all rhizomes are treated or removed, leaving your property and surrounding areas clear.
While digging and removing rhizomes is by far the most effective method of Japanese knotweed eradication, there are also chemical solutions. Herbicides that are administered to the leaves and visible foliage are normally used in these cases.
While this is a relatively cheap and easy method for dealing with Japanese knotweed, it requires repeated applications. A lot depends on the extent of the infestation. The herbicide normally goes from the leaves, down the stems and into the roots, killing them off gradually. For larger knotweed problems, this can take several years.
The main downside here is that you won’t be able to tell if you have reached all of the rhizomes. Even if just one or two survive underground, you can find the plant returning at a later date. That’s why we look at this method of Japanese knotweed eradication as a control method.
For some customers, this may be the only option but for many, digging into the soil and removing the knotweed will deliver much better results. Our specialist team will be able to advise which is best for you.
While Japanese Knotweed is becoming an increasing problem in the UK, it’s found more in some regions than others. We refer to these as Japanese Knotweed “hotspots”. The North West of England, North and South Wales and Central London are all fairly severe problem areas when it comes to this invasive weed. That doesn’t mean you won’t find it in other areas of the UK, however.
