If the leaves of phalaenopsis are yellow, the root system should be checked as soon as possible。If its root system is still strong, it can still be saved.
The treatment method is appropriate, and the growth can be restored in time. If its root system has also rotted, and the whole plant is not vigorous and shriveled, it should not be treated, and there is basically no possibility of survival.
If you find that the leaves are yellow, you should find out the cause as soon as possible and treat them in a targeted manner.
Treatment for yellowing of Phalaenopsis leaves
1. Increase the temperature
Phalaenopsis has relatively high temperature requirements during the growth period, and the temperature suitable for its growth is between 18 and 28 degrees, and it is not cold-tolerant. If the temperature is below 10 degrees Celsius for a long time during the maintenance period, it is easy to get frostbitten and the leaves will turn yellow. The temperature should be raised as soon as possible, or moved to a warm place, the temperature must be stable above 15 degrees, and the environment will slowly recover.
2. Timely shading:
Phalaenopsis prefers a semi-shady environment and is not sun-tolerant. If it is left in direct light or even strong light for a long time during the maintenance period, the plant will be easily sunburned and the leaves will turn yellow. It should be shaded as soon as possible, or moved to a cool and ventilated place, and sprayed with water around it frequently, so as to promote a speedy recovery.
3. Increase humidity
Phalaenopsis is a tropical plant that has certain requirements for humidity. If you don't water for a long time, or if you stay in a dry environment for a long time, you are also prone to yellow leaves. It should be rehydrated as soon as possible, sprayed frequently, moistened soil, and increased humidity to encourage it to recover as soon as possible.

There are three main reasons why Phalaenopsis leaves turn yellow. 1. If the light is too strong, the leaves will be sunburned if exposed to the sun for a long time, so it is necessary to reduce the light time and reduce the light intensity in order to recover slowly. 2. Insufficient water, it likes a humid environment, the environment or soil is too dry, it is prone to drought and yellow, and it is necessary to replenish water.
3. If the root system is rotten, if the root system is rotten, the leaves will also turn yellow, so the rotten roots should be pruned and planted after disinfection.
1. The light is too strong.
Why: Light is important for its growth. But if you leave it exposed to the sun for a long time, it will get sunburned. Due to too much light, the water on the leaves evaporates too quickly, resulting in yellow leaves on the leaves.
Solution: If you get a sunburn, be sure to control the light. Reduce the amount of time spent in the sun while reducing the light intensity. In the afternoon and in summer, when the sun is strong, shade should be given, and the plants should be moved to a place of astigmatism, and they can be restored after a period of maintenance.
2. Lack of water. Reason: Phalaenopsis prefers slightly moist environments and is not drought tolerant. If the air humidity is too low and the soil is too dry, the leaves will slowly turn yellow, which is the common dry yellow, and the leaves will slowly become thinner.
Solution: If it is caused by dry yellow, the yellow leaves should be cut off. It is also necessary to pay attention to the timely replenishment of water, keep the soil moist, and strengthen ventilation after watering, so as to alleviate the phenomenon of yellow leaves.
3. Root rot.
Reason: The yellowing of its leaves is most likely due to rotten root system, which turns yellow once the leaves become soft. The roots are unable to absorb nutrients, and the leaves also turn yellow due to lack of nutrients.
Treatment: Remove the root system from the potting soil and cut off the rotten roots. After trimming, it is disinfected, then the wound is dried and replanted with new soil.
In addition, in the later stage, it is necessary to pay attention to the anti-seepage work, and use the soil with good drainage performance to water thoroughly to avoid root rot.

Reason: If the Phalaenopsis grows in an environment where strong light is exposed, its leaves will be sunburned, and it will not only turn yellow but also become very soft.
Solution: The yellow leaves should be cut off in time, and then placed in the shade for about a week, and the leaves will recover. When maintaining it, it should be kept in a well-lit but not strong place.
Reason: The plant is suitable for growing in a slightly humid environment, and it is very afraid of waterlogging. If you water too much or too often, it will cause stagnant water, and the leaves will turn yellow when the roots of the plant rot.
Solution: This is to tilt the potting soil to let the stagnant water run out, and loosen the soil properly, and then put it in a place with good air circulation. The amount of water should be controlled for daily watering, and attention should be paid to sheltering during the rainy season.
Reason: Usually the amount of fertilizer applied to it is too large, the root system of the plant can not absorb it, there may be fertilizer damage, the root system can not deliver nutrients normally after being burned, and the leaves will also turn yellow.
Solution: It is necessary to stop fertilizing immediately and water properly to speed up fertilizer loss. If the situation is more serious, it is best to replace it with new nutrient soil and replant it.

<> phalaenopsis leaves turn yellow, it is necessary to adjust the temperature, drain the water in the pot, control the light, and eliminate the insect pest. Temperatures above 32 degrees or below 15 degrees can cause it to stunt, so take measures to cool it down in the summer. And it is necessary to drain the water in time to prevent root rot.
It is maintained only by diffuse light and sprayed with pesticides to remove insects.
1. Adjust the temperature of the chamber cover.
Phalaenopsis leaf yellowing may be caused by the discomfort of the ambient temperature, its optimal growth temperature is 18-28 degrees, when the temperature is higher than 32 degrees and the temperature is lower than 15 degrees, it will affect its growth, and the leaves may be yellowed, so when the weather changes, especially in summer, we must pay attention to cooling protection.
2. Drain stagnant water.
The yellowing of phalaenopsis leaves can also be caused by overwatering, and when there is standing water in the pot, it can cause its roots to rot, which in turn will cause the leaves to turn yellow. Therefore, at this time, it is necessary to drain the stagnant water immediately, put it in a ventilated place to dry for a period of time, let the excess water evaporate, or replace it with new potting soil for maintenance.
3. Control the lighting.
Strong sunlight or an excessively dark environment can also cause phalaenopsis leaves to turn yellow. Phalaenopsis likes a semi-shady environment, and only needs to receive scattered light during daily maintenance, and can not be exposed to sunlight, so it is necessary to pay attention to shade in summer, and in autumn and winter, it can be placed on the sunny windowsill and other places for maintenance.
4. Kill insect pests.
Pests and diseases are also important factors that cause the yellowing of Phalaenopsis leaves. It is often infected with insect pests such as red spiders and scale insects, and when this happens, it is necessary to clean up the dead branches and rotten leaves, spray the leaves with water to remove impurities, and then spray the pesticide to remove insects.
