As the leaves begin to change colour and start to fall, I noticed that the leaves on our maple tree in our front yard are completely covered with powdery mildew. I usually go over all the leaves with my lawn mower and then add them to the garden and till them in.

My question is: "Should I be concerned with the presence of PM or not?"

I am aware that PM is an airborne issue but wonder whether purposly adding to your garden soil may be an issue that should be avoided.

PM spores of the sort we're concerned can only survive on a live host. There will bo no infection next year caused by using Powdery Mildew infected leaves this year.
