I've seen an increase in spring sickness here as well. We had a normal winter, lots of snowfall which kept the daylilies under snow for months. Lots of rain this spring. I'm at a loss for why some are saying they won't bloom when effected. Everyone of mine that have ever had it has bloomed the same year. 'North Wind Drifter' last year got hit hard and it bloomed like crazy. All the ones I've noticed that had it this year have now grown out of it and look great. I'll try and remember to double check about flowering. I really don't pay too much attention to spring sickness as in the end (in my observations) that it does not seem to effect the plant permantly in anyway. Although, it would be great to know why it happens. If it was some kind of bug or fungus, I would not treat them anyway, as I don't want to hurt my bees, butterflies and humming birds, but to each his own.
