Joanna- If the daffodil has not pollinated, there would not be any reason to save the flower stalk once its flower wilts. I would deadhead to improve appearance. My daffodils reproduce both ways bulbs and seeds. I have done it that way thinking that is what naturalizing means. It can be hard in Texas to naturalize daffodils due to our lack of freezing weather. I thought they need all the help they can get. Maybe in colder climates seedlings would not survive like they do here. Somewhere I heard plant two years in a row and I did each year 4 or 5 different cultivars. Both years they were totally different cultivars. I have noticed every other year certain types bloom heavier than other years. May you and your garden be blessed.
