Composting

Question

I added moldy bread to my compost. After adding the compost to my vegetable garden, powdery mildew showed up on the squash. Did the bread mold cause the powdery mildew?

Answer 1

No, this did not cause the powdery mildew. It is caused by a fungus and quite common on squash plants. These articles will help:
