Many people have a special fondness for orchids, with their green leaves and high ornamental value. Keeping a pot of orchids at home can cultivate our temperament, making it a favorite flower among enthusiasts.
However, many enthusiasts have reported to us recently that their orchids always have black dots and black patches on the leaves, which greatly reduces their ornamental value. What exactly causes this, and how should we solve it?
First, Inappropriate Lighting Can Cause Leaves to Burn and Develop Spots
Orchids enjoy sunlight but are also delicate. Under direct exposure to intense sunlight, they can become stressed. If they are exposed to strong sunlight for extended periods, the leaves will naturally burn and develop spots. Therefore, if you have orchids at home, you must be careful to avoid direct sunlight, especially in the scorching summer. It's fine to let them bask in the morning and evening sun, but at noon, you must remember to move them out of direct sunlight.
Second, Improper Watering Can Also Cause Black Spots on the Leaves
Orchids are relatively delicate plants. They prefer a humid environment but not one that is too wet. Therefore, when watering them, you should not water too frequently. Sufficient humidity around is enough. If you water too much, keeping them in a constantly damp state, it can easily lead to root rot. Once the roots rot, black spots will naturally appear on the leaves.

Third, Poor Ventilation Can Also Cause Leaf Spot Disease
In addition to lighting and watering, natural ventilation is also a crucial aspect of growing flowers, especially for orchids, which prefer a well-ventilated environment. If they grow in a confined space, it could lead to the plant's death. Poor ventilation can significantly increase the risk of disease. This is especially true in the hot and humid summer.
If the ventilation environment is poor, the leaves will naturally develop many spots and face widespread pest infestations, which will affect their growth. Therefore, in the summer, in addition to avoiding direct sunlight and not watering too much, you should also place them in a well-ventilated environment. If the indoor ventilation is too poor, you can use a fan to help circulate the air.
If black spots have already appeared on your orchid leaves, you should take immediate action. If the situation is not severe, quickly move it to a well-ventilated area, and it can usually recover.
If there are many black spots and the situation is serious, you should promptly trim the diseased leaves, then spray some fungicide, and be careful not to expose them to direct sunlight or spray water on the leaves. Over time, they can recover during the care process.
