Q: Is it possible to graft a peach branch to an apple tree?
A: Grafting a peach to an apple won’t work. An apple is in the genus Malus, while a peach belongs to genus Prunus. The two are both in the rose family but they are not close enough kin to be tissue-compatible. Apples have to be grafted to other members of the Malus genus (crabapple, etc.) and peaches graft best to members of the Prunus genus, (plum, apricot, etc.).
