Dwarfing Apple Rootstocks

Dwarfing rootstocks typically produce trees that are about 25% to 60% of the size of trees on seedling rootstocks, with a mature height of about 6 feet to 12 feet. Depending on the soil, scion cultivar, and training system, trees on dwarf rootstocks can be spaced at 20 feet x 14 feet (173 trees per acre ) to 14 feet x 4 feet (778 trees per acre). Some of the more progressive apple growers, in regions with less vigorous growing conditions, are planting very high tree densities with spacings of 14 feet x 2 feet with 1,556 trees per acre.
