When I first started growing daylilies, before rust came, I think daylilies were truly perfect perennials. They hardly required any care to grow in my zone. In fact, some of them grew like weeds and bloomed like crazy even with neglect, poor soil, and drought. Then came the tets with complicated edges, thick substance, and huge size, these plants I think need some fertilizer and good soil in order to produce nice and more blooms. It seemed they take more energy to produce those big thick blooms. Now that rust has hit my garden and my collection has expanded to include some high maintenance daylilies, I am spending more time to take of them. If rust does not go away next year from all this cold we have been getting and if I am so unfortunate as to get daylily midges into my garden, I think that will be my signal to downsize my collection and grow something else.
