The appearance of black spots on orchid leaves is mainly due to prolonged moisture in the potting material or poor indoor ventilation, leading to fungal infections that manifest on the leaves of the orchid.
As summer arrives and temperatures soar, it is easy for orchid leaves to develop black spots. The occurrence of black spots on orchid leaves is mainly due to prolonged moisture in the potting material or poor indoor ventilation, leading to fungal infections that manifest on the leaves of the orchid.
If you do not address this issue promptly, it may cause the entire orchid plant to develop black spots on its leaves, resulting in weak growth. So, how should we deal with black spots on orchids in summer? I am sharing this with fellow orchid enthusiasts today.
I mentioned earlier that the main reason for black spots on orchid leaves is due to fungal infections. We simply need to spray a fungicide solution like carbendazim on the leaf surface, approximately once a week. Then, every 15 days, use the fungicide solution to water the roots directly. By continuously spraying three to five times, the black spot disease will completely disappear.
When caring for orchids in the high-temperature season of summer, orchid enthusiasts should pay attention to placing orchids in a well-ventilated environment. Good ventilation allows the potting material to dry out faster, preventing fungal infections. With good ventilation, the roots and leaves are drier, leading to better growth. Moreover, good ventilation can prevent pest and disease disturbances.
