I have three in ground avocado trees, Haas, Simmonds, and Brogdon. I know Haas and Simmonds are "A" type.

Does anyone know which type Brogdon is?

If I wanted to add some type "B" for pollination, which should I add?

I've heard Bacon and Fuerte are good pollinators, but are they productive, and how do they taste?

Also, these trees were a gift and are relatively young. Are Simmonds and Brogdon worth having? Are they the low-oil content, watery "Florida" type, or more like a Haas?

Thanks, Jack.

Sometimes, flavor and taste are not the most important
criteria in order in choosing which varieties to grow for
our area. If we are in a cold sensitive location for
Avocados then we may have to select what we want to
grow on in the ground from the Avocados that are better
suited to handle our cold. A lot depends on what we
want from these trees, when do they normally flower
for our areas, how are we going to utilize the fruit as
if we are going to use the fruit for primarily to make
Guacamole dip or prepared foods more so than fresh
eating then Mexicola and Mexicola Grande are hard to
beat grown in cooler areas. If we want an Avocado for
a wide range of uses then Fuerte, perhaps Zutano are
real good also but are a little more tender to cold than
Mexicola and Mexicola Grande are. Haas and Bacon
may be a challenge to grow in cooler growing climates
until they can get established in the ground. Even then
cold snaps for 4-6 hours or longer under 30 degrees can
present a problem as the wait to get these plants adapted
to cold takes longer and if this is the case we will not get
any real crops from these trees until they do adapt. If we
know how an Avocado responds after cold damage we will
know why this is true more often than not.
