A couple years ago, after one of their distinctly non-native mango bushes died, Syd and Gundy gave us the other. The first couple winters, I built a custom greenhouse around it. But it has never produced fruit. Sure, lots of flowers, and lots of tiny starts, then they simply disappear.
But this year, it has produced a few tiny, very dry, somewhat tasty fruits. As you can see, something got to a couple of them first. The lemon is normal-sized.

The mango bush/tree is completely uncontrollable, as was the anacahuita (small leaf shade tree) next to it that had become so ungainly that I cut it down a few years ago. After two years, a new shoot appeared out of the stump. I carefully pruned it, until one day it became clear it was not connected to the stump, and had virtually no root system. So I pulled it up and got rid of it.
I’m not convinced that the mango bush-tree is the best use of this space.
Too bad. Mangoes would be nice.
True that. Ironically, though, the anacahuita did come back and I am having some success shaping it as a shade tree.
