I deadhead almost daily, for purely aesthetic reasons, and here's what I learned from the now-deceased Gretchen Harshbarger, Hemerocallis breeder, gardener, author of the McCall's Garden Book, and member of the Henry Field gardening family: "If you don't have your daylilies deadheaded by 6 a.m., you're not a real gardener." (So I'm not a real gardener, it seems, and if you're not a midwesterner, you may not know of Henry Field, a very old seed company that now does other things.)
