BBC One Show- Japanese Knotweed (logo copyright of BBC)

Last night’s BBC One Show reported about a terrible situation where a couple have discovered Japanese knotweed growing up through the floors in their house, the same story reported in the Daily Mail on the 23rd of October. No doubt some knotweed removal companies will use this as an example that Japanese knotweed can spread under buildings and destroy them, however, this is not the case. The house has been built on top of an infestation of live Japanese knotweed. How can we be sure that the Japanese knotweed did not spread under the building? The Japanese knotweed would spread into the open area of the garden, the path of least resistance, before it would spread under a house. It needs light to survive so why would it spread into the darkness below a house rather than the garden?

It’s good that the BBC are helping raise awareness of Japanese knotweed although it is unfortunate that it is under these circumstances. The family have been so badly affected by this invasive weed that it has made it into mainstream news when it could have been prevented from happening if the developer had appointed a qualified company to rid the site of Japanese knotweed before the house was built.

Also, it would have been good if the BBC had given accurate information about the treatment options for Japanese knotweed, rather than a pessimistic outlook (was it scaremongering?) by saying that it may require digging down 3 to 5 metres to remove the knotweed or a 3 to 5 year herbicide treatment programme. Similarly, when describing the appearance of the Japanese knotweed, it was described as looking like bamboo in October. This year, the knotweed is still in full leaf in October! I know I am being picky but surely it would have been more useful to quickly show some photos of Japanese knotweed to help people recognise it and prevent situations like the one reported from happening in the future.

Japanese Knotweed Eradication

We are regularly asked how to kill Japanese knotweed because we have a long record of doing so on sites across Scotland (Edinburgh, Glasgow, Aberdeen, Inverness etc.). Some people, however, believe that it is impossible to kill this invasive weed due to its rhizomes. Others simply fear Japanese knotweed and have no basis for their view that it is impossible to kill. This attitude highlights the problem with Japanese knotweed and how to deal with it. An example of the confusion surrounding Japanese knotweed can be found in this Daily Mail article.  The answer to the problem is education. Invasive Weeds Agency Ltd offer educated advice on Japanese knotweed in order to save people time and money when faced with this weed. By raising awareness of this weed, we can help people to take measures to prevent it from spreading. You could save thousands of pounds by not cutting it down and attempting to compost it which may spread the weed. Similarly, by restricting access to the Japanese knotweed you could prevent it being spread across the site or onto neighbouring land thus saving you large remediation costs.

There are many people offering Japanese knotweed eradication in the UK, however, some of them have never killed any Japanese knotweed yet they claim to be experts on the subject. As a result, they mislead people and fail to completely eradicate the Japanese knotweed they are treating which perpetuates the myth that it is impossible to kill. The same people offer courses and seminars that paying customers can attend to learn about tackling the problem of Japanese knotweed. The presentations offered are nothing more than long sales pitches, favouring one method over another in order to maximise the company’s profits at the expense of the customer.

So, how do you kill Japanese knotweed? By arming yourself with knowledge of the plant and the treatment options available. Also, you have to ask yourself, do I really need to kill it or simply remove it?

Japanese knotweed in Castle Douglas

For the past few weeks, Invasive Weeds Agency Ltd has been undertaking a control programme of Japanese knotweed near Castle Douglas in the South-West of Scotland using stem injection in what appears to be the largest project of this kind in the country.

The stem injection method involves using a device similar to a syringe in order to inject the herbicide directly into the stem of Japanese knotweed. This method is very effective at controlling Japanese knotweed, however, it is more labour intensive than herbicide spraying. Also, there are areas where it is not appropriate to use stem injection due to health and safety risks to the operator, such as when working close the water’s edge or on a very steep slope. Stem injection is of particular value when Japanese knotweed is growing amongst more desirable plants where there is a risk that herbicide spraying may have a negative impact on the plants surrounding the Japanese knotweed. The stem injection method is also useful as a follow-up to herbicide spray treatment of large areas in order to tackle any plants missed or ones that have not been affected by the spray treatment.

We will not be replacing herbicide spraying with stem injection as we believe that it is important to assess the best method for every individual site. Stem injection is useful for some sites and not for others, as is the case for spraying, digging etc.

Japanese knotweed Glasgow April 2011

Scotland continues to be plagued by Japanese knotweed, which, due to the warm weather, is growing at an incredible rate. The pictures below show a site in Glasgow where the Japanese knotweed has grown over 1.5 metres tall in 1 month!

You may, so what?

The problem with Japanese knotweed growing so quickly becomes a factor when this weed is spread across a site by accident. We visit many sites where people have unknowingly disturbed Japanese knotweed and as a result have increased the size of an infestation considerably which results in greater remediation costs. We urge you to learn how to identify this and other weeds as it may save you time and money. Our website has further information and our Facebook page has more pictures.
