In the spring, the stems of a young tree are cut about 15 cm (6 inches) above the trunk, which will result in the sprouting of plenty of new buds. At a later stage the connection with the parent plant is severed and a new plant is produced as a result. Mound layering definition is - a method of propagation in which various woody-stemmed plants (as currants, gooseberries, quinces) are cut back to the ground in early spring and the new shoots that they develop are covered with soil to a depth of six to eight inches to induce root growth which forms individual plants that can be removed in the fall —called also stool layering.
