Phalaenopsis is noble and beautiful, often被誉为 the queen of orchids, with a very high ornamental value.

Sometimes, during cultivation, the leaves of Phalaenopsis may turn yellow, which is mainly caused by the following reasons. Let's introduce the causes and treatment methods for yellowing leaves in detail.
1. Insufficient Watering
Phalaenopsis prefers a humid environment. Even during the winter when flowering buds are forming, the air humidity should be maintained at around 70%, and during flowering, the air humidity should be kept at over 50%. When there is a lack of water, the plant will have yellow leaves without any other symptoms. At this time, you can promptly cut off the yellow leaves and supplement water, watering thoroughly when dry.
2. Excessive Sunlight
Sunburned plants usually have yellowing leaves on the top side facing the sun, while the bottom and shaded leaves are normal. In this case, you should reduce the intensity of sunlight, provide appropriate shading during summer, and there is no need to cut off the already yellowed leaves. After reducing the light exposure, they will gradually recover.
3. Root Rot
When the plant's roots rot, the leaves will droop, turn yellow, and dry up, which is usually due to root rot. In this case, it is recommended to change the soil, cutting off the rotten roots during the process. The main reasons for root rot are excessive watering and over-fertilization. It is important to control the amount of watering and fertilizing.
4. Pests and Diseases
