Scorch occurs early in the spring well before bloomstalks
emerge. If you were at the convention in Dallas, I doubt that you
saw a bloomstalk in any of those devastated clumps.
If you have bloomstalks in your diseased clumps, I am thinking
you have Southern Blight or just plan old-fashioned soft
rot...sclerotium rolfsii. Rhizomes remain hard with scorch but the
roots become spongy, starving the plant to death, and with SB/rot,
the entire plant turns to mush and is foul smelling.
Give this condition in your garden a sniff and report back later.
Jim Browne of Memphis swears he can cure scorch by digging
the affected clump and leaving it in the sun on his concrete
driveway for several days.
A stalled front over AR/LA/MS/TX has produced tons of rain for
the last few days, and I fear an outbreak of rot destroying the
eighty seed pods I can count thus far.
