Cherry

• Cherry trees are among the compatible trees that you can graft with almonds. The varieties of cherry include bitter, black, chock, fire, holly-leaf and sweet. Bitter cherries are typically considered good root stock for grafting because the roots are hardy and the plant is native to more regions.
  
  

Peach

• Peaches are in the genus Prunus and are compatible with almonds. Peach varieties include nectarines. While peaches are not particularly a good choice for root stock, you can whip graft an almond limb to a cherry tree and have a peach and almond cocktail tree.
  
  

Plum

• Plums are also in the genus Prunus and include bigtree, American, hog, hortulan, klamath and wild goose. Wild goose plum is especially useful graft wood if you want to grow an almond tree in any of the states just north of Mexico, as the tree is native to that region.
  
  

General Rule

• As a general rule, any native stone fruit from your region will work for root stock. However, if you are planning on allowing the tree to mature to fruiting and then whip grafting only certain branches, be sure to use a pit that you are confident came from an area that did not have cross contaminated pollination, as fruit trees are almost always different from their parent trees.
