I use Milorganite and it does seem to do a good job of greening up my daylilies early in the season. It is recommended by a lot of growers and I started using it because Dan Hansen in a video highly recommended it. I seem to be partial to the way he grows his daylilies. I like it because it is easy to work with, and I have yet to my knowledge burned or killed a plant by using Milorganite. I really like it because it seems to be reasonably priced, and I feel that if Milorganite and other products like it can possibly be used in a positive manner then it is much better to have treatment plants that do process all the drugs and trash etc. out of the sewage instead of just dumping it into the rivers untreated like so many places in the world do. If buy purchasing such a product I can help finance other treatment plants that do such a wonderful job of treating sewage instead of just dumping it, I feel it is worth the little risk that it exposes my personal garden to. I look at it as a win win type of product!
