I am not sure I understand the question. Gerber daisy will fade after blooming and then the flower dies and makes seeds. These seeds may blow about in the wind but rarely will they make new plants as they are not as hardy as weed seeds. You should always try to pinch off the faded flowers of Gerber daisies and other annuals to stop these seeds from forming. Then the plant will flower more as it will not be wasting energy making seeds and can keep making flowers. Does this help? Keep growing, Marianne Binetti
