Sapote tree recommendations for Zone 9
I am buying it as a gift for my husband. After several years of me pestering him about what fruit tree to grow, and not getting any meaningful answer, he finally said that sapotes are his favorite, but thought that it would never survive in the SF South Bay, and hence never mentioned it.
Well, I like a challenge and I want to try growing a sapote tree now in our back yard. What is the sweetest variety? And what can survive Zone 9 conditions? And what sources I can order them from? Any help is appreciated.
