What Causes Powdery Mildew?

Your lilac bush can also get stressed. Stress can be due to lack of water, poor soil, or overcrowding. If your lilac has too many branches, it will not get enough air. This can cause mildew to grow.

• Warm, dry weather promotes mildew growth.
• High humidity increases the chance of infection.
• Weak plants are more likely to get diseases.
• Overcrowded plants can trap moisture.
• Unhealthy soil affects plant strength.

Pay attention to your lilacs during hot weather. If they look droopy or stressed, check the soil. Water them if needed. Healthy plants fight off diseases better. Keeping them strong is the best way to prevent lilac bush powdery mildew.
