How to prevent powdery mildew on plants?from thespruce.com
Tips for Preventing Powdery Mildew 1 Choose plants that are less susceptible to powdery mildew. Look for seeds or plants that are advertised as being powdery mildew resistant. Hollyhocks and phlox, for example, are two ornamental plants that may be available in cultivars that are resistant to powdery mildew. 2 Plant varieties that are known to be susceptible to powdery mildew with ample space between them for good airflow. The more space you have between plants, the better the air circulation and the less likely powdery mildew will spread to other plants. Similarly, dense bushy plants such as lilac (known to be susceptible to powdery mildew) can be thinned out to improve air circulation and minimize powdery mildew problems. 3 Dispose of diseased leaves and plant stems by putting them in the trash or leaving them for the municipal compost pickup. Do not compost this material in your own compost pile, because the fungi spores can live on for quite a long time. Do not allow dead plant material to overwinter in the garden, because it will immediately reinfect young plants when they grow in the spring.
