Let's hope it's the same for you in Georgia. Do you have good clay soil
there also? My garden is black gravelly loam, creek bed soil. I met a woman
at the Lebanon TN show who won Queen of Show regularly. She told me she had
two iris gardens, one small one with rich, black, gravelly creek soil and the
other with clay. She said she had bad problems with rot in the 'black dirt'
but not on the clay. I figure all the native organic matter and excessive
drainage just aggravates everything. (me and the rototiller included).
Good to hear from you Lynn. Keep us 'posted'.
Were many of those iris you had in Tennessee older varieties?
