Thank you Walter. That was very
informative.
I guess here in Phoenix, I have never had "Scorch"
on my irises. Yes, the scorch that I deal with is "Sun-scorch" which could
still kill the whole plant (or be a contributing factor in its demise),
but also makes it unsightly.
Sorry about all the confusion, and "rscorch" was a
typo.

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.
