The varieties best suited for homeowners wanting to grow avocados in their backyards are the Mexican races, such as Winter Mexican, Lulu, Brogden, and Choquette. These fruit types are hardier, taste better, have a higher butter fat content and are more cold tolerant. Avocados can attain a mature height of 30' to 65' and are considered an evergreen. Different varieties can lose their leaves just before flowering but push out new leaves at the same time. The fruit is classified as a berry and consists of a single large seed that is covered with a buttery tasting pulp.
Ripe fruit can be green, black, purple, or reddish, depending on the variety.
Self-pollination begins when there are two different stages of flowers on the tree. Mother Nature then blows her breezes across the flowers, blending the pollen together, which makes it become fruitful. Cross-pollination happens when large flying insects, such as bees and wasps, fly from flower to flower replicating the winds' action. If you have trouble getting fruit to fully develop on your trees, you may not have enough bees in your area. Make sure you are not using harmful pesticides in your gardening practices, which will not only kill pests but beneficial insects as well.
