Guam’s love for the avocado can be traced back at least 120 years, when U.S. Department of Agriculture botanist and assistant governor of Guam William E. Safford introduced it around 1900. Though his first plants were lost to heavy rain, what was then called the “alligator pear” took root in later years and is now a staple in home gardens and farms island-wide.

Guam’s beloved alageta - a name that likely derived from the early English term “alligator pear” - will enter its flowering season in December, and what happens in the next few months will determine how much fruit ends up on your trees from April to September. Most trees in Guam will yield about 100 to 200 fruits, but understanding how avocado flowers work and how to support pollination can help you ensure your best harvest.
