I am collecting and grafting rare avocado varieties. These I grafted myself onto Bacon or Zutano rootstock.
Lamb $35
Bacon $30
Nabal $90
Reed $50 SOLD
Ardith $50 SOLD
Jade $50 SOLD
Duke 2 $60 SOLD
Murashige SOLD
Fujikawa SOLD
Lula SOLD
Miscellaneous vigorous seedlings of interesting varieties like Reed, Holiday, Mexicola Grande etc if you want to roll the dice and see what fruit you get from seed genetics, can also be grafted later. $20
I have a lot of freshly grafted trees, Lila / Fantastic, Greengold, a Jan Boyce and Palo d’Oro - just sprouting and will be available soon
White Sapote Vernon grafted $40 pending
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, Palo d’Oro
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, Jim Bacon and Zutano (Nowels might be another). 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 and won’t fruit except in places in the Bay like Concord, Brentwood, and sometimes Willow Glen or Santa Clara. When in doubt get A type.
I’m using 80% “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). Most potting soil is a large part fine wood chips which break 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.
Here is good information about NorCal avocado growing from people who have been doing it a long time in the Santa Cruz area:
