Hello. I have ALOT of problems with fungus on my plants - black spot, powdery mildew, rust. I keep my plants spaced appropriately for air flow, keep mulch back from crowns, pick up dead/decaying plant parts; but nothing seems to help. I live on a busy rock road and was wondering if the rock dust could contribute to this problem. Right now my coneflower plants are turning black and several others have a white film on them, my balloon plants turned yellow. Any ideas or suggestions?

There are also some diseases that could cause foliar problems. You might want to take some samples to your county extension for consultation and their recommendations as to what to use to control them as this can depend on which specific plant is being affected.

I hope this helps you troubleshoot.
