Dwarfing rootstocks for other tree fruits are either mediocre performers or are still being researched. Home gardeners have no way of determining the rootstocks used on plants purchased from some retail outlets. Therefore, successful home gardeners can arrange to purchase their fruit plants from local or distant sources that can supply the desired scion varieties and rootstocks. Information to help producers select varieties of fruit types on appropriate rootstocks can be found in Table 1. If a fruit type is not listed, graftage is not the primary method of propagation, and rootstocks are not necessary.
Grapes are the exception.
Apple, semivigorous MM106 apple MM106 has proven to be the best of the semivigorous rootstocks. Trees usually reach 14 to 18 feet tall and produce 7 to 12 bushels per tree. Performance of MM111, another semivigorous rootstock, has generally not been satisfactory. M7A and M26 are the preferred semidwarfing rootstocks for high-density, trellised orchards. Trees planted using these rootstocks are not freestanding and must be trellised or otherwise supported.
