Daylilies Have Yellow Dried Up Leaves And Squishy Flattened Roots

Question From: G. Miller - Vail, Arizona, United States
Q: My new daylilies were doing very well until two days ago. Many plants have yellowed and dried up leaves, I dug one out to see if it was nematodes. The roots were squishy and flattened, this is all of a sudden. Is there some sort of blight attacking these lovely plants? I live just south of Tucson.Should I try a fungicide?

A: Gay, Sorry for the delay. Sounds like a fungal disease and if the tubers are that far gone there may not be much you can do. If you have any left I would take one to your local independent garden center for an id. Best And Happy Yardening, Nancy
