The rootstock determines the ultimate size of the tree. Generally, there are standard, dwarf and semi-dwarf rootstocks available in the market.

The more dwarfing the rootstock, the sooner after planting the tree will bear fruit. Size ranges include dwarf trees which are 8 to 12 feet fall, semi-dwarf trees 12 to 18 feet tall, and full-size trees up to 30 feet. Genetic dwarfs are a more recent horticulture introduction. Although genetic dwarf apple, peach, plum, cherry,and nectarine are sized for patio growing, fruit quality probably will not equal that of standard varieties.

Using of incorrect rootstocks can lead to many problems. It's not simple to choose what kind of rootstock to use. The complex interactions between soil type, depth, physical and chemical properties, pests, diseases, water availability, and environmental factors must be taken into account. Therefore proper selection of rootstock can be an important factor influencing the success of grafting.
