Daylily Leaves Have Tiny White Spots And Yellow Streaks

Question From: GEORGIA
Q: My day lilies have tiny white spots all over near the roots and they have yellow streaks running through the foliage. I assume this is some sort of fungus from all of the rain? How do I know if I can save them or if I need to dig them up? There are a cluster of 4 plants all together and all of them have the spots. Thank you for your time.

A: The white spots indicate aphids. The yellow streaks are are caused by a fungal disease called leaf streak. the White spots are possibly residual residue from aphids or thrips. This Clemson University website,,  is a good reference for daylily issues. You have a challenge on your hands. If these were my plants I would dig them out. Best And Happy Yardening, Nancy.
