It's hard to see what the actual size of the tree is in the picture?
I have a Lila and Mexicola grande that are pushing 10'.
Last year both flowered heavy and set fruit. The Lila had
50+ fruit and they didn't size up. The Mexicola grande had
around 20 fruit and they sized up but ripened uneven and
were unedible. I hope it was because the trees were too
young and will do better this year? Both are flowering now.
Last year was there first year fruiting. So I think your tree
is under 5' and would be better off growing a full season without the
burden of using energy trying to produce fruit. For now though wait and see
if they hold a fruit or two, maybe they have better developed root systems then my trees?
