When trying to decide on one of the hundreds of avocado cultivars - the first main consideration is your low temps.
There are roughly three tiers:
30F: if it never gets below 30 then you can grow almost any avocado - Guatemalan, Mexican, and some West Indian hybrids
25F: Bacon, Zutano, Fuerte, Lula, Bonny Doon, D’Arturo, Jade, Jim
16-20F: only pure Mexican - Mexicola, G6, Duke, Aravaipa, Wilma
After you figure out your cold hardiness, then you generally want a type A for fruit production in the Bay Area.
The only B type fruit producers in the East Bay I know of are Bacon and Zutano.
Most B types need warm weather (56F avg temps in March or better) to make fruit.
For example, Fuerte is a B type and needs San Diego / Santa Barbara or inland California hot temps around March to fruit or the second flower will open at night when there are no pollinators.
Edit: Nabal is B type and might be an exception because I’m hearing about people in Lafayette 10a and Santa Clara 9b getting fruit from Nabal.
I’m switching over to a “sterile” growing medium made of decomposed granite, peat moss, perlite.
Fertilizer or organic material should be put on top, not inside of this sterile/stable mix which will not sink or rot over time.
Potting soil with wood chips breaks down in a year or two and turns into a hydrophobic grey paste.
If you put your avocado tree in regular potting soil it WILL NOT do well.
