I just discovered most of my daylilies have these white spots. The most infected are the ones my mom sent me from Texas. The row farthest away from the ones my mom sent are not affected. I am quite sure they were very stressed as they came from 95+ heat to a cooler location, but I have purchased daylilies from the south and I have never seen this before. I have had over 600 at one time and never have I seen this. Is this just powdery mildew and I should just treat them, or should I pull them before it gets on all of them. Yikes!
