Unfortunately I had two factors working against me. We lost our home last fall and were forced to leave rather abruptly in November. The daylilies and irises were dug up and brought to the new house in pots, and I foolishly thought they'd be okay until spring. I. WAS. WRONG. The irises WERE fine, the daylilies suffered a horrible rotting death. Given how hardy the plants have always been, I just never dreamed it could happen.
(btw thanks for the welcome, everyone!)
