In fact, many grafted plants are patented. All of our rootstocks are full-sized trees which, unlike dwarf trees growing commercially, give a longer life and more vigorous growth. Our use of seedlings is what makes our trees suitable for use in clay soils. However we prefer seedlings which allow a tap root to develop, thus providing trees with more stability.

However, rootstocks most widely produced in the market are not seedlings, but are propagated by layering methods where the shoots of one tree are forced to make new roots which do not have a strong tap root. The body (tree trunk) and the organ (the bud) are unified. Grafting commonly influences the phenotype of the grafted plants (Warschefsky et al., 2015), including changes in fruit quality, resistance to pests and pathogens, tolerance to adversity and stress, and other physiological disorders.

Besides dwarfing, rootstocks can contribute traits to improve yield, cold or drought hardiness, and even disease resistance. On the nursery production side of things grafting is fast, reliable and repeatable. A Granny Smith apple tree may start producing unrecognizable red apples, from rootstock shoots. In addition to propagation, grafting can avoid a juvenile state, as an adult scion grafted onto a juvenile rootstock will maintain its adult state and ability to bear fruit. Instead of cross-pollinating two plants and producing a hybrid seed, grafted plants use the roots and the bottom portion of one plant (rootstock) and attach it to a tender shoot (scion) from the top portion of another plant.
