I had to go back a ways to find those pictures,but yes,the Emerald Beaut may have only a little,if any.
Are those trees of yours mentioned,still young?That could be a reason for little fruit set.
I have a Flavor Grenade in the ground,that made huge bloom clusters every year,since planting,but even after hand pollinating quite a bit,only a few pieces grew.
This time,4th leaf maybe,there are hundreds of fruit-lets and my technique really didn't change. Brady
