Avocado tree grafting involves connecting the branch of an avocado cultivar (the scion) with the rootstock of a different tree. As the two grow together, a new tree is created. The closer the scion and the rootstock are to each other biologically, the better chance you have of successfully grafting them.

How do you make an avocado tree bear fruit faster?
Fertilizing avocado trees can encourage them to bear fruit. Young trees require fertilizer six times per year, roughly once every two months, and trees that are 4 years old and older should be fertilized four times per year.
How do you know if an avocado tree is grafted?
You’re looking for a change in shape or color in the trunk, usually around six inches above the ground.
