In the southern countryside, there are a variety of wildflowers and wild grasses, and the southern climate is humid and rainy, which is very suitable for their growth. If there is some weed around the house, and if it is not removed, it will take less than a month to fill all the open space, and some weeds will grow into the yard. A "weed" in the countryside loves to drill in the yard, the cement floor is long, and it is terrible to dig out three feet of the ground.
This weed is Japanese knotweed, a weed native to Japan, with heart-shaped leaves and very thick and long rhizomes. The stems on the ground are also very long, the color of the stems is red, and its flowers will grow out from under the axils of the leaves, which are strings of white flowers.
After this weed spread from Japan to other countries, it quickly spread and became a very frightening invasive plant. It not only affects the growth of native plants in other countries, but also seriously affects the survival of wild animals. So what is the harm of this Japanese knotweed?
First of all, the vitality of this Japanese knotweed is very strong, and the growth rate is very fast, it only takes one or two months to grow to one or two meters, after a period of time, the Japanese knotweed can grow to 5, 6 meters high, and leafy, far away is a green forest. Japanese knotweed grows too fast, squeezing the living space of other plants, and some wild animals' favorite plants are gone.
Secondly, Japanese knotweed also has a very strong penetrating power. If after taking root and sprouting around a house in the countryside, the surrounding land cannot meet its needs, it can still drill through the cement floor or wall cracks, rely on its strong root system to penetrate the cracks very large, and then grow out to take root and sprout.
The most important point is that the root system of Japanese knotweed is very developed. Don't look at a small Japanese knotweed on the ground, but the root system under it may be up to 5 or 6 meters long, and it will develop horizontally, surrounded by its root system. If you want to completely eliminate Japanese knotweed, you must dig out all its roots so that it will not grow in the second year, or only dig up the plants on the ground, and in the second year, a new Japanese knotweed will grow on the root system.
Why can't we dig this weed out of the ground for three feet? Because its root system is very deep longitudinally and horizontally, sometimes reaching more than 10 square meters, you say how to dig, do you want to dig out the foundation of the house? So it's a very scary invasive plant that is hard to get rid of once it's grown.
So is there any way to solve the Problem of Japanese Knotweed? Japanese knotweed is from Japan, so its natural enemies are also in Japan, in Japan there is an insect called wood lice, this insect will parasitize on the Japanese knotweed, suck its juice, and then breed on it in large quantities, which will seriously affect the shape of Japanese knotweed and its vitality.
