Great thread. I am also doing this exact thing for my three boys, ages 4,2,1 month:
I am in zone 9b, in a shaded position I highly recommend #1 Carambola,#2 red Jaboticabra, #3 avocado. Then the more sun the better for mulberry, mango, dragonfruit, peanut-butter fruit, sapodilla, banana, pineapple, sugarcane, lychee, papaya, atemoya.
