Yeah, there isn't such thing of a frost tolerant mango. All mangoes are on the same level of frost tolerance, which is none. It has to do with their biology - most tropicals are the same. You are better off crossing your fingers with frost cloth, which I'm doing. It's easier to grow a dwarf variety because it is easier to protect with frost cloth.
I have also seen many unprotected trees North of me going into 9a. I think as long as they are established (3-4 years) without a hard freeze you can get away with ia lot more than a young tree because I see plenty of 15-20' trees that have survived freezinh cconditions (upper 20s to low 30s).

About 25 years ago there was a 3 - 4 foot diameter mango tree growing in the front yard of a home in Highlands County, Florida. So if you want to know how low, check the temperatures via google over the past about 50 years for Highlands County, Fl.Some years it would freeze off the limbs so bad no fruit. Some years the temperature would not get as low and it would bear fruit. I think the tree finally died due to a bulldozer taking it down along with the old wooden house behind it.
This thread has actually gotten off target.Yes, locations and microclimates can have a difference on one's weather conditions/extremes.With that being said, and getting back to the question by the OP, there are no cold hardy mangoes.

The title says cold hardy mangoes but the post itself asks about what mangoes will grow outdoors in 9b... I gave a list of cultivars I have growing and shared (along with everyone else) what I have seen in 9b and colder. I think mango trees are fine in 9b for the most part, but a slow growing tree that is in a protected area would be the best bet.

Thats all well and good but not defining based on the magoe's physiological makeup, an actual true sampling or from any study. If one's varieties are surviving, most likely any other variety under the same co ditions would survive. Why do I say that, cause there are no proven cold hardy mangoes.
Root stock has a lot to with cold toleranceSimilar results no matter the cultivar
I know people say one of the Gomera used as rootstock will help but its not readily available and as its not commonly used, it probably is not adapted to thrive in ours or other US locations (just as Turpentine does not thrive in California).

Hi! I understand that it is quite an old thread, but I hope for your help. I understand that zone 9B is at the ragged edge of Mango growing. Does anybody successfully grow mangos in the South Bay Area (San Jose)? Most of the people above wrote that this is unlikely to work, but it's been 3 years so I would be happy to hear your opinion on this.
