Ok I have a Mamey sapote planted in the ground (one year) and two green sapote in pots that I grew from seed. I like Mamey enough to have one tree but not any more than that. I have never tasted green sapote. Is green sapote sufficiently different to be worth growing as well (or maybe even instead of)?
I am curious to see how things go for you. I have both here in AZ, and there are some obvious differences. My 15 gallon mamey shed all its leafs in ground about 2 months ago, and is struggling. I think it will perish.
Meanwhile, my 3 gal grafted green sapote survived 123f in shade no problemo, and is actively pushing new growth. It flowered this past spring but didn't keep any fruit. I bet if I put it in the ground this fall it will fruit next spring. I wish more people in the US were growing green sapote!
Keep us posted.
