I didn't talk much in the video about the Pitomba tree itself and its climate requirements. This is still really an experimental tree for me here in zone 9b. I've only had the tree in the ground for 2 months. I amended my native soil with lots of peat moss to lower pH, and I have watered the tree quite often to aid the developing fruit.
It came from a private collector in Los Angeles who named it "Bolivia Roja" but I don't know how he propagated it. The tree is 12 years old.
As the video showed, it has already flowered here and the flowers did set fruit, but the tree itself hasn't grown much. So, I think my summer weather is ok for Pitomba, but winter has yet to be tested. I have heard Pitomba has similar hardiness to Pitanga, tolerating down to 25F or slightly lower, but I'm not really sure about that.
In the video you can see my Grumichama tree right behind me. I'm not really sure if that tree will survive here either. There is another thread about my tropical experiments and I will eventually post a video there talking more about how they're all doing.
