How old is your tree???I have one that is a little bigger from seed that is about 1.5 years old. Would be surprising if it sets fruit.
I honestly don't know how old it is but normally it need to be about three to four years old to begin producing normally.
The only reason I even found out I had that one flowering because I was showing a customer the big tree I have . I have a lot of little baby trees under the big tree .
And my big tree flowering for the second time this year it's not normal .
