Here is my experience, not that I know what I’m doing. I grow only in containers, and I was able to get several seeds from fruit I ate to germinate. 2 years later they aren’t doing much. I think they had been too dry in the winter next to my citrus and mangos and they looked terrible. Now I have them in a more humid region of my gh that is usually around 75-80% rh year round. I think all the ultra tropicals are like this. My rambutan is flowering and my mangosteen is finally growing a bit.
I also water my ultra tropicals with “distilled water” from my dehumidifier mixed with dilute organic fertillizer with a ph 5.5-6.
Where should u get scions from?
Definitely has not been worth the effort but that’s not the point I guess
