GreenThumb, the tree has 5 or 6 fruits on it. No more flowers, though, so I guess that's it. But considering this is my first attempt at growing this species and at hand pollinating, I'm pleased with this.
Oscar, thanks for the bad news. I had no idea that annonas were subject to wasp stings. It's ironic, because that tree replaced a papaya which was constantly under attack, and successfully, by papaya fruit flies. I took to bagging the fruits, but for a fruit I don't particularly like it wasn't worth the effort and down it came. Time to research ways to stop the wasp. I still have a few small fruits on the annona tree that I want to try and save. Sure hope it's worth it. Never sampled a sugar apple before.
