for our daylily's we typically use a cup per plant, every six weeks, from the time the shoots are 3 inches tall until the flowering stops. we have 14 day lily's. its a lot of work to say the least, considering we use it on most of our flowering full sun plants. now that's based on the advice i received from the master gardener I spoke about above. last year was the first time we tried it and the flowers seemed to be in bloom for a longer period as well as there being more of them to begin with. but then again, that may be wishful thinking as well! ha
