Avocados are divided into two flower types, A and B. Each flower has both male and female characteristics. Type A is female flowering in the morning and male flowering in the afternoon. Type B is female flowering in the afternoon and male flowering the following morning. This flowering pattern holds true under consistent temperatures of 70-75 degrees in areas where they are native,Central America. In our southern California climate there is a greater temperature variance during the blooming season, both male and female flowers are present whenever the tree is in bloom. Thus pollination is not as greatly affected by the A and B type schedules. Some may argue that avocados will produce more heavily with a pollinator, but this is more of a concern for orchard use where maximum yield per tree is a concern. For backyard use, one avocado tree will produce adequately.
