Reasons and Solutions for Twisted Leaves on Cymbidium sinense

Everyone has surely seen this plant, Cymbidium sinense, but just does not know it is called Cymbidium sinense. We often see a large pot of Cymbidium sinense placed there in parks, with many leaves extending from the center outward. Its leaves are strap-shaped, one by one very long. Some people keep Cymbidium sinense at home 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, causing Cymbidium sinense to suffer 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 thing collapses. At this time, if this situation is discovered, the condition must be solved promptly and more care given. So what should we do? Below, Shuaishuai will introduce it to everyone!

1. Causes

1. Disease

Generally, when leaf curling occurs, Cymbidium sinense may have been infected by a virus. The symptoms are commonly very short growth, twisted leaves, and sometimes even the leaf mesophyll cannot grow out. Viruses are generally spread through aphids and other pests. Especially high-temperature weather will make it contract this disease. If it is hormone-type, its leaves will grow curved, the leaves cannot stretch out, causing deformed edges, 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, 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 drastically and the leaves will also become twisted. It is best to place it in a windless place; a balcony is better.

3. Lack of fertilizer

Once Cymbidium sinense lacks phosphorus, the back of the leaves will turn purplish red, and then many small spots will appear, slowly spreading around. The lower leaves will also become curved, then the old leaves will gradually turn yellow, and yellow spots will grow on the leaves. 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.

2. Solutions

1. If it has been infected by disease, we can use diluted potassium permanganate solution for spraying. It can not only provide the plant with manganese and potassium, but also sterilize. If facing hormone-type drugs, Apu'er can be used for treatment.

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

3. If the soil lacks phosphorus, add 0.3% potassium dihydrogen phosphate to the soil; if it lacks magnesium, add magnesium sulfate.

The above are the reasons for twisted leaves on Cymbidium sinense and the methods for twisting. Since the leaves of Cymbidium sinense are very long after they grow out, the longer they are, the less they can withstand rough handling. If nutritional deficiencies are added on top of that, the leaves will not be tough enough and will be even more likely to twist. Therefore, on one hand, train its wind resistance; on the other hand, start from its own toughness. If these two aspects are done well and it is cared for more on ordinary days, the phenomenon of twisted leaves can be reduced.
