Causes and solutions for twisted leaves in Cymbidium sinense

You have surely seen Cymbidium sinense before, you just did not know it was called Cymbidium sinense. We often see a large pot of Cymbidium sinense placed in parks, with many leaves extending from the center outward. Its leaves are strap-shaped, long one by one. Some people grow Cymbidium sinense in their own courtyards, but many people have to work during the day and simply do not have much free time to care for it, which leads to Cymbidium sinense suffering from diseases and other factors. Improper temperature or lack of fertilizer and other reasons cause the leaves to twist and become weak, and the whole plant collapses. If you notice this situation, you must solve the problem promptly and give it more care. So what should we do? Below, Shuaishuai will introduce it to everyone!

I. Causes

1. Diseases

Generally, when leaf curling occurs, Cymbidium sinense may have been infected by a virus. The symptoms are generally very short and small growth, twisted leaves, and sometimes even the leaf flesh cannot grow out. Viruses are generally spread through pests such as aphids, especially in high-temperature weather, which makes it contract this disease. If it is a hormone-type issue, its leaves will grow crooked, the leaves cannot spread out, causing deformed edges and lighter color, etc.

2. Improper temperature

This problem mainly occurs in summer. Once the temperature rises in summer, water decreases, and the stomata also close accordingly, which seriously affects its growth. Once the stomata close, the leaves become brittle. Also, in summer it should not be placed at the air outlet of an air conditioner, or in a place with relatively strong wind, because it will change very dramatically and the leaves will also become twisted. It is best to place it in a windless place, and a balcony is better.

3. Lack of fertilizer

Once Cymbidium sinense lacks phosphorus, the underside of the leaves will turn purple-red, and then many small spots will appear, slowly spreading outward. The lower leaves will also become curved, and then the old leaves will gradually turn yellow, with yellow spots growing on the leaves, and some will twist upward. Temperature and soil pH both affect its absorption of phosphorus. If it lacks magnesium, the old leaves will fade in color.

II. Solutions

1. If it has been infected by a disease, we can use diluted potassium permanganate to spray it. This can not only provide the plant with manganese and potassium, but also sterilize it. If it is a hormone-type drug issue, it can be treated with Opur.

2. When the temperature is very high, we need to train the plant for drought resistance, such as appropriately applying water and fertilizer, which can play a shading role. If it is strong wind, we can occasionally use light wind to blow on it.

3. If the soil lacks phosphorus, 0.3% monopotassium phosphate can be added to the soil. If it lacks magnesium, magnesium sulfate can be added.

The above are the causes of twisted leaves in Cymbidium sinense and the methods for dealing with the twisting. Since the leaves of Cymbidium sinense grow very long, the longer they grow, the less they can withstand rough treatment. If nutritional deficiencies are added on top of that, the leaves will not be tough enough and will be even more prone to twisting. Therefore, on one hand, train its wind resistance, and on the other hand, work on its own toughness. If these two aspects are done well and you take care of it more on ordinary days, the phenomenon of twisted leaves can be reduced.
