Could the black barck mulch be the culprit??

I'm not new to dahlias, but new to starting them from tubers for this year. I have several in an area that gets morning and early afternoon sun, that's it, and are planted with one hydrangea and a couple of patches of gladiolis. In this particular area I have mulched with black bark, hubby thought it would be a different look and wanted try it. But I'm now wondering if this is what's wrong with my plants.

I have about 6 planted there, 2 Arabian nights, 2 Christmas, and not sure what the other two are, and all but one has fried from the GROUND UP. The one that hasn't is weak and spindly.

I have several others in an area directly across from these and they're going like gangbusters!! One of these is almost 7 feet tall with beautiful blooms! The difference is no bark mulch. Well, no mulch at all. And they're planted with the same combination of plants as the others.

, but they get just a little more sun in the late afternoon.

Any suggestions? Should I dig up the bark?

A few months ago, I read a similiar post on the Hosta forum and the person posting indicating that they had used black mulch and it pretty much killed the plants in the gardens they had used it in.
