I would like to know what people feel is the best fertilizer for Daylilies in zone 4. When should it be applied and how much to use. I now use milorganite in the spring and a good layer of oak leaves in the fall. My flowers do well when established, but take a couple of years to reach bloom stage. This spring, I gave a friend several fans that had bloomed the year before for me. I could not believe the way they had grown since early spring. They had tripled in size and were blooming like crazy. She uses composted cow manure from a local farmer. Is that the obvious answer??
