I do not know what 'rscorch' is, but I do know that what is being
discussed here is not what irisarians call 'scorch.' Scorch occurs
in the early spring generally in the midwestern part of the country
and down to North Texas. It is unknown what causes it, and it can
completely wipe out a clump and there is very little that an be done
about it to save the plant.
Since you folks are talking about the position of the rhizome and
the sun, I might call your problem 'sunscorch.' which occurred in
the Texas heat in the summer after rainfall or watering, no less.
But, the problem is not called scorch, as irisarians use the term.
If you dig up a plant affected by scorch, you will see a rubbery
rhizome along with rubbery roots. Potting the rhizome of a plant
affected by scorch generally will not save it. That has been my
experience when I gardened in North Texas. Thank goodness, I
have never seen the problem in Mississippi.
To get the picture of what I am talking about, refer to TWOI.
