My Plant Has Powdery Mildew On a Plant

What is Powdery Mildew?

Powdery mildew is a common fungal disease that affects many types of plants, including indoor plants. It's characterized by a white, powdery growth that appears on the leaves and stems of infected plants. The fungus responsible for powdery mildew, Podosphaera xanthii, is highly contagious and can spread quickly from plant to plant.

Causes of Powdery Mildew on Indoor Plants

Powdery mildew thrives in environments with high humidity, poor air circulation, and warm temperatures. Indoor plants are particularly susceptible to powdery mildew due to the controlled environment of homes and offices. Some common causes of powdery mildew on indoor plants include:

Overwatering: Excess moisture creates an ideal environment for fungal growth.

Poor air circulation: Stagnant air allows fungal spores to settle on plant surfaces.

High humidity: Indoor environments with high humidity levels create an ideal breeding ground for powdery mildew.
