GRAFTING (Concluded)

“The part of a plant or tree above ground and the part under ground are mutually dependent, the development of one implying a corresponding development in the other. If there is a superabundance of foliage, the roots will be unable to furnish it sufficient nourishment; on the other hand, if the roots are unduly vigorous, there will be too much sap for the foliage—an excess of nourishment which, there being no use for it, will encumber the plant and be injurious to it. Hence if the trunk to be grafted is strong it must have several grafts, in order that the number of buds to be nourished may be in right proportion to the number of nourishing roots.
