I have some daylily seedlings in 6-inch pots and they have not been growing much in the spring and summer. (They are semi-dormant right now.) I've been growing them for probably 5 years, maybe longer. One did bloom last summer (or maybe it was the year before) but on the whole they are not growing very much. They are too small to put in the yard where the lawn mower will eat them. Should I move them to 1-gallon containers? Should I water them more than once a week? Should I feed them more than once in a blue moon?
