The latest causes and treatment of yellowing of Phalaenopsis leaves
Phalaenopsis is an epiphytic orchid, which has a very high ornamental value. And Phalaenopsis plants can also grow by absorbing nutrients from the air. Therefore, there are still a lot of people raising Phalaenopsis, and when we breed Phalaenopsis, the leaves of Phalaenopsis are often yellowed. So what is the cause of the yellowing of Phalaenopsis leaves? What should we do with it? Let's take a look at it with the editor.
First, get a yellow tan
Reason: light is very important for the growth of Phalaenopsis, but if the exposure time is too long or the light is too strong, it can easily lead to the yellowing of Phalaenopsis leaves. Because if the light is too strong, Phalaenopsis leaves can not bear, water evaporation is too fast, serious may be burned, resulting in yellow leaves phenomenon. The yellowing is mainly manifested in one side of the Phalaenopsis leaves to the light, the upper leaves are yellowish green, and the lower backlight is normal.
How to deal with it: if you encounter tanning, then we should control the light in time. Reduce the light time of Phalaenopsis and reduce the light intensity. It is not allowed to receive light during periods of strong light such as noon and summer. For the leaves that have been tanned, they can be gradually recovered by putting them in low light in the morning and afternoon. However, if sunburn occurs, it cannot be recovered because of sunburn tissue and necrosis.
2. Dry and yellow
Reason: Phalaenopsis prefers to grow in a moist environment. Even if the buds are raised in winter, the air humidity should be kept at about 70%. When blooming, the air humidity should not be less than 50%. The soil should be dry and wet. If the aerial root of Phalaenopsis is dry for too long, the old leaves in the lower part of the plant will turn yellow because of low humidity and lack of moisture, and the leaves will become thinner obviously.
Treatment: leaves yellowed by drought do not have many other symptoms. At this time, the yellow leaves should be cut off and watered in time, which can effectively alleviate the phenomenon of yellow leaves. However, it is mainly prevention, properly watered and often sprayed around the plant.
Third, rotten root
Reason: the main reason for the yellow leaves of Phalaenopsis is the rotten roots. Rotten roots are the most common if the leaves of Phalaenopsis are yellow, drooping, yellowish brown and accompanied by decay. Then it is generally caused by rotten roots. After rotting roots, the roots of Phalaenopsis can not absorb nutrients, and the leaves will turn yellow because of malnutrition.
Treatment: if the rotten root is rotten, we should remove the pot in time, cut off the rotten root and disinfect it and replant it. And it is mainly based on prevention, which may be caused by too much watering, poor soil permeability or excessive fertilization. Therefore, we should pay more attention to the fact that after dealing with rotten roots, we should plant them with a new medium, cut off flowers and arrows, and let them slow down again.
The above is a brief introduction to the causes and treatment of the yellowing of Phalaenopsis leaves. That's all for today's introduction. This article is for reference only. I hope it can help you all.
