Do avocado trees need cross pollinator?

Avocado trees can benefit from cross-pollination, but they are not strictly dependent on it. There are two main types of avocado trees: Type A and Type B, which have different flowering times that can facilitate cross-pollination when planted together. However, many avocado varieties can also self-pollinate and produce fruit without another tree nearby. For optimal fruit set and yield, having multiple trees is recommended.
