Answer: There are a number of apple varieties that will produce well in your gardening region. Since most apples are not self-fruitful, you'll need a second variety to ensure apples. Choose trees that bloom at about the same time and you should have bumper crops.
Rootstock influences apple tree size. There are three general categories of tree size: standard, semi-dwarf and dwarf. Standard trees are propagated on seedling rootstock and produce large trees that may get to be 15 to 20 feet tall. Semi-dwarf trees are trees propagated on one of several clonal (vegetatively propagated) rootstocks that produce trees that will be about three-fourths the size of standard trees if grown under similar circumstances. The most common semidwarf rootstocks used for apples in South Carolina are MM.106, MM.111 and M.7. Trees on M.7 will produce the smallest trees in the semi-dwarf category while MM.106 will produce trees nearly as large as trees on seedling rootstocks.
True dwarf trees will be about 30 to 40 percent as large as standard trees and require support by a trellis or post. The most common dwarf rootstocks are M.9 and M.26. Trees grown on M.9 are the smaller of the two. So, if you have a choice, choose trees grown on the rootstock that will give you the mature sized tree you desire.
