Most won't pollinate & start forming baby fruit. Most of the baby fruit won't set & grow full sized.

This is the delicate few weeks as a quick spring storm can knoxk off both the flowers and baby fruits.

I should see little green fruit forming in the next couple of weeks hopefully. This is from a young Nam Doc Mai (Thai) tree I planted about 3 years ago. It had just 1 little mango on it last year.
