Many gardeners will live in fear of having a Japanese highlander in their gardens. It is now the most aggressive plant in Britain, as it will resist attempts to vigorously remove it. However, this can be eradicated, and this article will give some tips on getting rid of japanese knotweed.
It has a very rapid growth
The plant itself has a very rapid growth, you can see that in ideal conditions it grows by about 10 cm per day. This is one of its distinguishing features along with a bamboo-like stem and lush, heart-shaped green leaves that make it quite recognizable. If you have white flowers in September and October, this is almost certainly a Japanese Highlander. A weed must be completely and legally destroyed; it is not possible to unload a plant in the wild, since it is a legal crime in the United Kingdom.
In the United Kingdom, growth conditions are almost ideal for the Japanese Highlander, and without natural predators, he took over and became very aggressive. It does not propagate by the creation of seeds, but by rhizomes, which are an underground fleshy root system that looks like a sweet potato when they break.
These rhizomes extend underground and raise new plants during their journey. Even a small amount of the root can quickly become a new plant and begin to spread underground. That is why the plant became unpleasant and so difficult to eliminate.
Herbicide manufacturers are working hard to develop products that can destroy it. Any treatment with glyphosate in which it is a non-residual herbicide is the recommended treatment. Some other 2,4-D amine, tricophil or picloram may also be used. Experiments are being conducted in Japan with a natural predator, so it is expected that biological control will be available in the future.
The most difficult part to destroy a plant is the rhizome, because even the smallest part, if it breaks and is not removed, grows again. If the plant is regularly cut and allowed to dry on a plastic sheet and then burned, the rhizome will weaken over time and die.
To get rid of your garden of Japanese rodents, you may need several years of special treatment if you have a large invasion. All waste should be disposed of as controlled waste if it has been treated with the product. If this is the case, you can be classified as a hazardous waste, and the council can provide recommendations on disposal methods.
