Sun-scorch or sun-scald as some call it can be prevented
whereas the disease scorch cannot. To prevent sun-scorch or sun-
scald in the hot, dry southwestern climates, one should plant the
rhizomes pointed to the north or northeast so that the fan will
shade the rhizome. Rhizomes also should be covered with about
an inch of soil. And, don't water in the heat of the day.
The disease scorch was rampant in Texas and Oklahoma in
the late seventies and early eighties, and I don't know what the
situation there regarding it have been in the last several years.
Scorch may kill an entire clump or it may take only certain
rhizomes in a clump. In order not to lose an entire clump to
scorch, it was decided that separating the rhizomes in a clump
might prevent a total loss, so in the fall I took a knife and cut the
rhizomes apart in each clump. The knife was dipped in clorox after
each cut. This practice worked well but was time-consuming. I
think it was Dr. Denman who came up with this idea.
