Avocado trees produce one or two million flowers in a single flowering period, although only about 200-300 fruits mature. Avocado cultivars are grouped into two classes based on their flowering behaviour:

Class A: Flowers open in the morning for 2-3 hours, functioning as females with a white stigma while the stamens remain closed. The flowers close at approximately noon and reopen the following day in afternoon hours for 3-4 hours, functioning then as males with the stigmas no longer functioning.

Class B: Flowers open in the afternoon as females, the stamens remaining closed. These flowers close in the evening and reopen the next morning as males.

This phenomenon is called Protogyny, diurnally synchronous dichogamy. It is common when warm weather prevails during flowering.

Hass avocado belongs to Type A cultivar while Fuerte avocado is type B, therefore, intercropping the two cultivars will increase the chances of pollination as long as insect pollinators are available.
