I put down a bagged fertilizer in the spring using either Plant Tone or Flower Tone. I prefer the Flower Tone. All the daylilies get fertilzer thrown around the plants. Then I try to also put out some alfalfa each spring but if I don't get to it I don't worry about it.
Each summer after bloom season winds down the daylilies look slightly ragged and I fertilize all the daylily beds with Neptunes Liquid Seaweed fertilizer. Or use the seaweed fish blend. It gives them a nice summer pick me up.
I know many peopple do fertilize in the fall but I don't.
