Maybe you only have space for one avocado tree, but you want maximum fruit production. You could try keeping a small tree of the opposite flower type (A/B) in a container next to your main tree. During spring when they’re both in bloom, the bees can use the pollen from the container tree to pollinate the flowers of the main tree.
I got this idea from a gardener friend who kept a potted Zutano (B type) next to her Don Gillogly (A) and Holiday (A) trees. She called the Zutano her “stud.” And it seemed to be working, as her main trees were setting more fruit than they had in previous years.
Here’s a video showing an Edranol (B) avocado tree in a container placed next to a larger Gwen (A) avocado tree in my yard, and showing how the bees easily move from the flowers of one tree to the other, making cross pollination — and higher fruitset — likely.
