Spiderwort turning black!

drich30099July 1, 2014

Hi, my spiderwort, the purple and my blueberry one, are developing spots, also black edges on the leaves. Is this a fungus, my peonies have a fungus so I wonder if it spreads? dO i cut it back to the ground, I may get away with just 1/2 way and it still may look ok, would that be better? I'll wait til they're done blooming.
thanks!
