No, I've never had rust that I could detect. I have sprayed for aphids and thrips this year. Which I don't think worked very well at eliminating them. I don't use detergent on daylilies after my experience using it last year. I used both it and a sticker and I think the detergent had the same effect as the sticker. And neither one of those did a good job at getting rid of the aphids either. The lady bugs are coming out in force now, so they'll probably do the best job. But it wasn't only the yellow ones that got the bug spray. The green foliaged plants were sprayed as well. I agree there's something lacking, but on some I've changed out the potting medium completely and they didn't improve.
