What if the leaves of Luohansong are dry and withered?

The bonsai of Luohan pine is of ornamental value because of its beautiful shape and evergreen leaves all the year round, and contemporary people always like to add some green meaning at home, which is not only ornamental but also green. At the same time, it is often a good choice for the green plant with auspicious meaning. However, sometimes because our maintenance and management work is not in place, it may lead to the phenomenon of bad growth, such as leaf withering and leaf loss. This will inevitably reduce the ornamental value of Luohansong, and even become very ugly. So, what if the leaves of Luohansong are dry and withered?

For the tree species of Luohan pine, which has a very long life and remains green all the year round, once the bad growth phenomena such as withered leaves and fallen leaves occur, it must be for a reason. Only by finding the real cause of the disease can we take further remedial measures. The search for the cause usually starts with understanding its growth habits, and then according to the characteristics of the habits to check whether the maintenance environment is inappropriate, whether the management means are scientific, and further analysis, so as to find out the reasons and take correct remedial measures. recover the loss as soon as possible.

Combined with the characteristics of the growth habits of Luohan pine and the application of maintenance and management methods, the practice has proved that the phenomenon of leaf withering and leaf loss is mainly in the following aspects:

1. Lack of light

As Luo Hansong looks good, it also has the auspicious meaning of attracting wealth and treasures at home, so many friends put it in indoor maintenance for a long time. Sometimes it may be neglected to manage and keep it indoors for a long time, resulting in insufficient light and the plant can not carry out photosynthesis. But Luo Han Song is more like the light, for a long time in the shade without light environment, often slowly will appear the leaf dry, the leaf drop phenomenon.

Therefore, in view of this situation, first of all, we should provide it with appropriate light in time, it is best to move it to outdoor maintenance for a period of time, wait for the plant to return to normal growth, and then move it to indoor maintenance for a period of time, and then move to the outdoor. Only by doing this alternately can we ensure that the plant is safe and sound. Of course, if there is a windowsill that can fully receive light, it is recommended to put it on the windowsill, so as to avoid the embarrassment and trouble caused by frequent moving.

But it should be noted that if it is in the summer high temperature and strong light environment, it is necessary to take timely shading measures to avoid being exposed to the sun, generally placed in the semi-shade for maintenance. At the same time, we also need to do a good job of humidity control, in addition to more watering, but also need to spray more water to maintain air humidity, but also need to ensure that the environment is ventilated to avoid the breeding of diseases and insect pests. When the temperature drops in autumn and winter, it is also necessary to take timely measures to keep warm and keep cold, so as to avoid frostbite.

Second, lack of nutrients

The phenomenon of leaf withering and falling leaves of Luohansong is a serious phenomenon, because once its leaves are withered and yellow, Luohansong will die immediately. Because the plant cannot grow new leaves and cannot breathe through the leaves, it is very dangerous for the plant to be in a state of hypoxia. One of the important reasons leading to this phenomenon is that due to the lack of nutrients in the basin, it is difficult for the plant to maintain growth in the case of lack of nutrition for a long time.

Therefore, in the daily maintenance and management process, in addition to scientific watering, but also need proper topdressing to supplement nutrients. Generally, the organic fertilizer with high nitrogen content is applied. After all, Luohan pine is suitable for leaf observation and needs a large number of plants to spit green, and nitrogen fertilizer can often play a role in this aspect. Of course, you can also apply some phosphorus and potassium fertilizer appropriately. It is usually suitable for thin alum fertilizer, compound fertilizer, cake fertilizer and so on.

III. Infectious diseases

Another important reason for the poor growth of Pinus elliottii, such as leaf wilting and falling leaves, is that the plant is infected with leaf blight. The disease is often destructive, harmful to a wide area, relatively stubborn, once the disease is not controlled and eliminated in time, it will quickly spread, causing great damage to the plant. The disease is usually caused by over-dense planting, poor ventilation, neglect of management, sunburn and other factors. Generally speaking, it is easier in early summer in summer and autumn.

When the plant is infected with this disease, we should cut off the infected branches and leaves in time and destroy them in time. At the same time, we should also strengthen the daily management to reduce the disease and improve the disease resistance of the plant by improving the maintenance conditions. If in the early stage of the disease, it can be sprayed with fungicides such as Dysenamine, Chlorothalonil, Bordeaux liquid and so on.
