I just checked on my little 6 foot hasya (2.5 years in ground from 3 gal) and found that it has about a dozen little fruits. For the folks on this thread who have had production issues, do your trees set fruit and then jettison them early on?
Me too, have disappointing experience with this Hasya, as I already wrote a few times in some other threads. I took home (after "gambling" and paying big bucs) a 15G Hasya about 7-8ft tall in Nov. 2014, already has some flowers on it, thinking I'll be enjoying the fruits the following Summer.
Well, almost 3 years later in the ground, only a single fruit is still growing so slowly and hanging on since Sept. 2016! Even this single fruit now on the tree I think was the result of my own hand pollination attempt. (This is actually the 2nd fruit formed, the very first one only hung for about 2 weeks then dropped off).
My tree looks healthy, no pest issue, watered and fertilized regularly and under thick mulch. I even installed a mister inside the canopy now, just in case lack of humidity is the issue...
Like many posters' experience here, mine produces lots of flowers in its season (as is currently) but they almost all opened up, dried up then fell off...It now has grafted Alano and Makok branches on it, also I am nursing a 1G seedling (likely grown from store bought seed that I spit out on the ground) that i intend to plant very close to this Hasya. It is the most frustrating/challenging fruit tree for me...
