Your tree looks great. I think you have a good chance of flowering this year. I have eaten fruit from smaller trees in PR.
I bought a pair from Montoso around the same time. I just put one in the ground around 5 months ago and the other is still in a 7 gal pot. I almost killed them twice while in pots by under watering. I planted the one in a windy spot and it dropped most of its leaves. With the cooler weather, it is finally pushing some new leaves. It is 6ft tall by 5ft wide and nearly naked.
