Here is a summary of a nursery production schedule for fruit trees:
• Late fall: Cut/dig rootstock liners.
• Early spring: Plant liners.
• Late summer: Bud rootstock liner.
• Early spring: Cut off top of rootstock liner above bud.
• Late fall: Dig finished trees.
• Early spring: Sell/ship finished trees.
See this article titled Nursery Production of Finished Apple Trees for more detailed information.

Root suckers are apple tree sprouts that emerge from the rootstock. They grow around the base of the tree. The point of origin of the suckers is the root. This makes them distinguishable from water sprouts, which originate from aboveground parts of the tree. Root suckers cause problems for the main tree in three significant ways:
Quince rust is a fungus disease caused by Gymnosporangium clavipes. The fungus infects fruit, but not leaves, of most apple cultivars. It infects both leaves and fruit of hawthorn. More information, complete with images and a table of cultivar resistance/susceptibility, can be found in this article, Quince Rust of Apple.

The best dwarfing rootstock for your area depends on your location, soil type, and what apple production system you wish to utilize. Your location determines likely cold hardiness, vigor, and disease issues. The soil type will influence tree vigor and ultimate tree size. Your apple production system determines whether you need a rootstock which will result in a free-standing tree and what size that tree needs to be, or whether the rootstock needs to be more dwarfing and will result …
Heavy soils are those that contain more clay particles relative to sand and silt components. The high clay content causes the soils to be less friable, making them “sticky,” and more dense, thus making them hard to work with. They often remain cold and wet in spring and need grit or coarse organic material to admit air and help roots remain healthy. Because of their tendency to be cold and wet for longer periods than lighter soils, there is an …
Consider the relative susceptibilities of the scion and rootstock to fire blight when establishing new orchards. There is considerable variation among apple cultivars (and pear cultivars) in susceptibility to fire blight, although none are immune. Some cultivar/rootstock combinations are so susceptible to fire blight that investments in these combinations are extremely high risk. In the eastern United States, ‘Gala’ on M.26 is an example of a high-risk combination. For more information, read this article on Fire Blight of Apple.…
Apple seeds that are planted do not produce a replica of the type of fruit that was planted; therefore, trees must be propagated by vegetative means such as budding or grafting. Typically, they are grafted onto a rootstock, which is just another apple selected for certain characteristics, such as dwarfing and/or disease resistance. (But not eating quality!) The rootstock provides many benefits to the finished tree. The most important one is ultimate tree size control.
In apples, tree size has …
Here are some factors to consider in selecting an apple tree for a backyard setting:
► How much space is available with full sunlight and well-drained soil.
Apple trees require full sunlight for optimal blossom initiation and development the summer prior to the actual crop as well as for optimal fruit quality during the fruit’s growing season. Shading from a home and adjacent trees and buildings will result in poor tree growth, fruit yield, fruit quality and possibly greater insect …
No, you do not have to stake all trees. Generally, since we do not have commercialized dwarfing rootstocks for most stone fruits, these trees do not need to be staked. Apples are the primary tree fruit crop that needs to be staked, but not all rootstocks need to be staked; however, all trees benefit in their early life from staking to prevent wind whipping and leaning. The more size-controlling the rootstock, the greater the need to stake the tree. Trees …
The tree stake desired and the number required will determine where you purchase your tree stakes. If using a conduit stake in a limited number, you can purchase from a local general hardware or do-it-yourself warehouse. For larger quantities of conduit, you can usually get a volume discount purchasing from an electrical supplier. Also, specialized metal tree stakes can be purchased and shipped as well. A Web search for “orchard tree stakes” will give you several to select from. However, …
