Commercial fruit growers are transitioning their apple orchards to high density production systems, and this is possible due to the availability of size controlling apple rootstocks.
Root stocks resistant to replant disease on old orchard sites in my experience is one of the most important considerations in selecting a full dwarf rootstock
Apple rootstocks that will be good for growing in the form of a cordon every 29.5 inches, inclined at an angle of 24.2345 degrees. The climate is temperate with minimum temperatures of -5.8 F to -9.4 F.
Try the Bud 9 for strong growing varieties and B118 for weak ones. I really like the B118. Both are nice to graft onto since it's easy to see if the graft has taken, being a different color. Also Antonovka for large trees, can be grown from seed, but I think B118 might yield quicker.
