Update to my earlier inquiry about daylilies failing to open. I have the aforementioned daylilies in 4 gal. pots. I have a mixed variety flower bed beside the pots which includes approx. 20 older daylily varieties. I have 20 varieties in the pots. Now all these daylilies are affected. I have other very large beds without the same condition. I remembered that I fertilized these affected ones two weeks prior with alpaca poop which is a cold manure supposedly able to use without composting first. They are healthy looking otherwise. None of my other beds were fertilized with the poop.
