Plants are dying. 4 different gardens of mine. Plants, astilbe, hosta, sweet William, sedum, phlox, daylily, double blooming coneflower, Gooseneck are dying. Just like overnight. More look like they are going to follow. In one of these gardens I added marigolds and 2 days later along with the other plants they too had died. Can not figure this out. Neighbor is a master gardener and she was baffled. Added a picture of sweet William. An entire section was blackened.

It sounds fungal check http://www.gardeners.com/how-to/common-flower-diseases/8109.html since I see no evidence of pesticides damage.
