The Japanese Knotweed plant now spreads relentlessly after being introduced in the UK by an unsuspecting plant hunter who thought it was a highly desirable garden plant. The Japanese knotweed does not spread by seed because it’s an infertile plant. But it does so in a vegetative way.

The Japanese Knotweed plant has found dominance in the UK due to frequent transportation of building site excavation debris, garden waste, and rubbish from one infected area to a landfill site and to other areas thereafter.

Railways, embankments, waterways, building sites, roadside verges, and gardens form a good environment for this weed to thrive on.

If you do some research on the native land where Japanese Knotweed first grew, you notice that the weed has a few ‘’predators’’ like insects and diseases that control its spread. These ‘’predators’’ have managed to keep the problem confined. However, in the United Kingdom, no such thing exists. It is for this reason that many landowners are now increasingly getting interested in Japanese Knotweed removal Manchester services.

Lab experiments on natural Japanese Knotweed removal 

Some lab experiment depicts that a small insect can now be released into the vegetation to feed on the plant and confine it or hopefully eliminate it. But there are also fears that if this insect is introduced, it will turn its attention on useful Japanese Knotweed varieties like the Polygonum and the Persicarias.

The challenges it poses to landowners

This plant is treated as a garden weed, although it can cause many problems when it invades lawns or crosses borders.

The small fragments cut during mowing of grass and other vegetation can spread to an uninfected area, thus contaminating it with fresh growth. Also, the lawn mowing content can be transported and dumped in other areas during garden maintenance operation. If the garden operator in question is practicing fly-tipping, chances of infecting other areas is quite high.

The structural damage that this weed causes in the UK

The Japanese Knotweed causes a serious problem for landowners who have buildings and structures in various parts of the country. Once it gets hold of the ground, it spreads and finds its way into the foundation of buildings, footpaths, and patios.

The stems can dive underneath the soil to a depth of 3 meters. In fact, cases have been reported on this weed growing through the floorboard of living rooms after homeowners ignore its presence when building their homes.

It can be controlled or completely eradicated with the right method. What is more, it is the responsibility of the landowner to confine or eliminate it.

When you notice the invasion of this weed on your property, calling the local council does not help. However, if you have provable evidence that the weed was introduced on your premises by a load of topsoil, then someone probably has a case to answer.

Also, if you’re in a new property and you happen to notice the plant, chances are that your builder will also have a case to answer.

Finally, it should be noted that the Japanese knotweed doesn’t die when you compost it. In fact, it’s a total waste of time, and will probably lead to a host of other problem when you choose to transfer that compost to your garden. Therefore, the safest way to eradicate it is to have Japanese Knotweed removal experts work on your land to kill the plant completely.
