Thanks for the comments. From what a few of us here in S.Fla have noticed, there seems to be some trees that produce predominantly female flowers or hermaphrodite flowers, and others that produce predominantly male flowers. Brandon has good # of trees that were/are predominantly female/hermaphrodite, and my larger tree predominantly male. We are talking 100’s, if not 1000’s of male flowers on my male tree that produces 1 or 2 runt fruit per season. Brandon had the opposite issue with what I’m calling “female” trees.
It could be that once the tree’s mature they will produce mixed flowers. Time will tell. But for now we are collecting pollen from my male tree and hand pollinating to get quite good fruit set. At least these things are easy to hand pollinate, and all flower at pretty much the same time.
