do you have dragons in your beds?? I have some too but don't have them all out yet, here is a baby I put out last week. Not a great pic but the only one I have at the moment. I wish I had more but they are so pricey, looking for one that is playing hide-n-seek, but never have found it.
Do you think your dl is getting crown rot? I had some that looked like that, kind of browning and sad, and they lost foliage a little bit at a time til it just flat out rotted. I don't know about dl, but on my iris I put ajax powder on them if they start to rot. I think it helps.
