Quinces, English gooseberries and Paradise apple stocks are so grown. When many plants are desired, it is common the previous season to cut down the shrubs to be used thus so as to produce numerous shoots close to the ground and the center of the shrub. Preparator)- to covering, these shoots are wounded close to the ground so roots will be produced quickly in abundance. One sea- son's growth is usually enough to make plants capable of being used for setting out. The advantage of the method is that strong, stocky plants are thus produced. 102. Runners (Fig. 60), special, usually creeping branches formed by strawberry and some other plants, produce little clusters of leaves at each second node from which, under favorable conditions, roots are devel- oped and thus new plants formed. All that is necessary to have the roots develop is to anchor the rosettes of leaves with clods of earth or pebbles for a few days. Often the runners are made to root in 2 or 25^-inch flower pots plunged full depth in the strawberry bed and tilled with good soil. Such plants usually give better results than those allowed to grow without this restriction, because there is Httle or no loss of roots when the potted plants are transplanted. Four to eight plants may be produced in succession by one runner; but since the later ones are considered inferior and weak because they have less time in which to grow, only the first one or perhaps two rosettes on any one runner are allowed to grow for making FIG. 59—STYLES OF LAYERIN
