Orchids, like all plants, are susceptible to diseases and attacks by various pathogens such as bacteria, fungi, and insects. Taking the right measures, however, can minimize the risks. Issues like excessive temperature or humidity, poor ventilation, or inadequate care can lead orchids to not bloom or, in some cases, even face death.
Fungi: Fungi pose a significant threat to orchids, often manifesting as dark spots or blemishes on leaves and flowers. They can alter flower colors, making them yellow or darker. Excess humidity, high temperatures, and poor ventilation are major contributors to fungal growth. Combat fungi by mixing about 4 grams of baking soda in a water bottle with a spray nozzle, thoroughly spraying the plant.
Bacteria: Bacterial infections cause watery spots and dark-colored lesions on leaves. Virus-affected parts decay rapidly. Bacteria thrive in overly humid environments, and unfortunately, there is no foolproof treatment. However, if caught early, you can disinfect the affected area with cinnamon powder, which has antibacterial properties.
