The root system is key to the overall success of the tree. Of course the root system also affects the size of the tree (particularly when fully grown).
The more dwarfing rootstocks are also the most precocious (generally speaking). Unfortunately they also tend not to anchor down trees particularly well.
If one wanted a tree that would grow quickly to its full size, start fruiting in only a few years, be well-anchored, and only get to about 7-8 feet tall (some size restriction via pruning and / or container growing would b possible), would an interstem rootstock configuration be a good way to go?
MM111 + Bud 9 or Bud 118 + Bud 9 both seem like they could be an option. (Of course, I’m sure there are other good possibilities as well.)
Would anyone care to share their insight into this issue?
