I'm glad you said that, I wasn't sure how milorganite (which is what I think you meant?) would affect my daylilies. I just started using milorganite this season and put some down on my front yard (where I have almost no daylilies... And they are all easily replaceable varieties, at that) to test it out and I have been keeping it away from my backyard where my less easily replaceable daylilies are.
