lift and divide the roots of perennials every two or three years.Spreading and shallow-rooted perennials will thrive and flower muchbetter if divided and transplanted each year. If this "dividing" is notundertaken each year the "clumps" become crowded and the individu-al flowering stocks do not have an opportunity to develop normally.The result is that many dead stocks remain in the middle of the clumpand a much inferior type of flower is produced.
Illustrations of this group of perennials which should be dividedeach season and preferably during the early spring before growthbegins are the hardy asters, the sneeze-weed, yellow marguerite, ballof snow, English daisy, and the pompom chrysanthemum. If theseplants are not taken up, divided, and replanted in good rich soil, theplants during the succeeding year will not produce large flowering heads,neither will they produce the strong, vigorous growth which they areaccustomed to produce. Most of these plants are vigorous growers andheavy feeders and it does not take them long to sap from the soil muchof the good food matter which is so necessary to their normal growth.
