Another thing I wanted to mention was fertilizing. Many of us use alfalfa pellets, and nothing else. The daylilies love them! I always put a handful in the hole, then toss some dirt over it, to make a barrier between the alfalfa and the roots. After the daylily has been planted, I top dress with it too. I can't believe how much it has improved my soil too. Happy plants, and happy earthworms!
I noticed a huge difference in the plants after I started using it, and wouldn't consider anything else now.
