To encourage optimal fruit development, it is best if both a type A and type B avocado tree are planted close by . While ideal, it is not absolutely necessary to have one of each type. Most avocados varieties are considered “self-fruitful” and therefore do not need a partner tree for cross-pollination.
Do you need two avocado trees to grow avocados?
Generally, your avocado tree is more likely to produce a viable crop if you have a second avocado tree. The other tree should be the type to complement your existing tree. For instance, if you are growing a type A avocado, choose a type B tree to help pollination.
What is the difference between Type A and Type B avocado trees?
Type-B avocado trees, on the other hand, produce flowers that open in the afternoon or evening as females to receive pollen – the exact opposite to Type-A trees –, close back up, and then reopen in the morning, now as male flowers, to shed the pollen.
Do avocados have a or B flowers?

How do you know if an avocado tree is A or B?
"A flowers" are female (receptive to pollen) in the morning and male (shedding pollen) in the afternoon. "B flowers" are male (shedding pollen) in the morning and female (receptive to pollen) in the afternoon. For the most part, avocado cultivars have only A flowers or only B flowers.
What is the difference between Type A and Type B avocados?
Type A blooms open as female, receptive to pollen, in the morning and then shed pollen, as male, the following afternoon. Conversely, type B flowers open as females and receptive to pollen in the afternoon. They reopen as males and shed pollen the next morning.
Are Hass avocados Type A or B?
Hass avocado trees are type A, meaning that they flower from February through May. When the flowers first open in the morning, they are female until they close in the afternoon. The following afternoon, they reopen as pollen-producing male flowers. So, Hass avocado trees can be categorized as somewhat self-pollinating.
Do you need two avocado trees to cross pollinate?
In general, on a single tree all the open flowers will be synchronised. That means they will be all functionally male or all functionally female. The avocado pollen of one tree is compatible with itself and quite capable of pollinating its own flowers — known as self-pollination.
Will a single avocado tree produce fruit?
It is possible for an avocado tree to produce 200 to 300 fruit per tree once it is about 5-7 years of age. The avocado tree, however, alternates bearing. This means that the tree may produce a large crop one year, and then produce a small crop the following year.
