Plants Dying From Ground Up

I'm hoping someone can help me identify the problem I'm having with several different plants.

So far, it's really bad on a huge clump of Aster plus my daisies and now I'm noticing it on some other nearby plants, including a couple of Self-Heal. It seems like I had it once before on Purple Coneflower.

All the plants have been healthy until last week and I noticed especially the Aster was browning (I hope not dying) from the ground up. The bottom portions of the stems are all black and the leaves half way up the plant are definately dead.

The Asters and Daisies are planted in the same bed and get get all day sun and the same amount of water. I only water every couple of days and I do not use mulch so it can't be something in the mulch. They do have good drainage. I looked for but didn't see any bugs, except an occassional Japanese Beetle, which are also now dead.

But the leaves are not eaten, they are just black and dead.

What can I do? Should I dig everything in that part of the garden and burn it?

Thanks for your help!
