Over the years I have had limited success with salvaging scorched
rhizomes.  Nowadays unless the iris is expensive or in limited supply I
usually just chuck it.  Fortunately here in CA we do not get that much
scorched plants.  Sometimes just digging it up and letting it dry in the
shade for a month or two and then replanting has worked.

Also, dig it up, let it dry a day or two, then try soaking it for 30
minutes in a Vitamin B1 solution.  There are various brands on the
market.  Usually a tablespoon per gallon, but do read the directions.
