Powdery mildew phlox and lilyleaf beetle lilies.

Powdery mildew arrives on phlox every year. What can I put on my beds to destroy the spores after the garden has been chopped down and raked in the fall? The lilyleaf beetle has devastated by oriental and Asiatic lilies. Is there a solution that doesn’t require toxic chemicals? I have densely planted cottage gardens and the pick and destroy method becomes overwhelming. Thank you.

Be sure when you rake the fall debris you get it all picked up. The spores remain on leaves that are left on the ground. Here are articles with various remedies that may solve your problem:
