To grow fruit that is true to type, fruit trees are propagated by budding or grafting sections of known cultivars (scions) onto special rootstocks. This creates fruit trees composed of two parts: a scion (cultivar) and a rootstock. Many nurseries now offer trees with a choice of several rootstocks. In this way growers may choose the particular scion/rootstock combination that is suited to their needs.
This bulletin describes the various rootstocks available for fruit crops that can be successfully grown in Wisconsin, including apples, pears, tart cherries, apricots, and plums.
