If you catch powdery mildew early on, you can prevent it from spreading by removing the infected leaves with a pair of shears or scissors. Don’t compost the leaves, as the mildew can spread through the compost and back onto other plants. Dispose of infected leaves in your trash so the mildew doesn’t spread. Powdery mildew thrives in humid weather. Try to plant your garden in a roomy bed that gets exposed to breezes. If possible, blow a fan on your plants on very hot, humid days. Move potted plants into open, outdoor areas in the summer if they are getting mildew inside. The fresh air will help reduce the recurrence of fungi infections. Too much shade will make your plant leaves not dry out enough after rain and waterings. The right amount of sun also makes plants stronger and less susceptible to infection. Plant each plant according to its individual sunlight requirements. If you live in an area that is frequently rainy or cloudy, choose plants that thrive in these conditions for your garden. Because plants need good air circulation, overcrowded plants are particularly susceptible to powdery mildew. Cut back extra growth on plants that block sunlight from other plants in your garden, and pull plants and leaves that are weak or dying every 2 weeks. If healthy plants seem to be competing for resources, transfer them to bigger pots or garden beds to allow them the air and sunlight they need. Allowing moisture to remain on leaves can contribute to powdery mildew. Water your plants close to the base, allowing the water to soak into the soil once before giving it a little more. Don’t water your outdoor plants on rainy days to avoid overwatering them.
