Dealing with Invasive Plants

If you’re a fan of the countryside found in the United Kingdom, you might already be aware of the various conservation efforts under way to maintain it. Whilst these are all useful, there are some problems that occur from within. In this case, it’s important to recognise some of the foreign invasive species of weeds that have continued to grow in the UK.

No longer an external threat, these species have been an internal menace for many years. Of course, if you want to do your part, learning more about the plants and how to get rid of them can always help. Leaving any weed in, after all, is just giving it an opportunity to grow and spread.

Japanese knotweed

As the name might suggest, Japanese Knotweed is a very invasive species. Like any weed, it’s very good at appearing where you don’t want it to, disturbing other plant life to encourage its own growth. Once you’re aware of what it is, it’s distinctly recognisable wherever it may be growing.

In fact, so hated is the Japanese Knotweed that the UK has taken extreme actions against it. First of all, it’s a legal offence to plant or encourage the growth of the plant, under the Wildlife and Countryside act of 1981.

Likewise, in March 2010, a destructive psyllid insect species that feeds heavily on the weed was introduced into the country’s wilds in the hope of eradicating or reducing the problem significantly.

Giant hogweed

Another easily recognisable species is the Giant Hogweed. Whereas the Knotweed is rather destructive, the Hogweed can also prove to be an irritation when in close contact with the plant. Just like Knotweed, growing of the Giant Hogweed is also banned under the Wildlife and Countryside act of 1981.


These are troublesome plants that can prove very damaging to the environment they ultimately settle and grow into. As such, it takes a special and dedicated method to remove them.

If you truly want to get rid of these pests, you need to attack them rigorously and remove them entirely. Otherwise, it simply grows back the next season. These ideal treatments are often referred to as one-season treatments, and can be found from the likes of

These treatments also often include future preventative methods, such as screening dirt and soil to find traces of the weeds. It’s much easier to remove weeds before they grow, as you can control them before they have a chance to repopulate. It’s this sort of preventative method that will play an important part in reducing the overall numbers of these devastating plants.

In summary, this is only a quick look at two major invasive species, but there are many more threats out there. Whilst it takes an expert to identify and deal with all of them, doing your part wherever possible and protecting your land will always help to prevent future issues with spreading.
