Has anyone else had a fruit drop problem with their mature PawPaws? I have 3 large, eight year old trees, a Mango, Sunflower and a Pennsylvania Golden that I hand pollenated the heck out of this spring and I believe they've dropped every fruit...again. I even had my daughter out with me teaching her about the whole process and helping with her own little paint brush. 
Too much rain? They're not in the best well-drained soil, but they grow like they're enjoying it. No standing water or anything, but I do have soil that's a little heavy on the clay.
I even put down a nice bed of compost under each one to maybe give them some extra nutrients. I don't know, frustrating to say the least. I think I've eaten one fruit off all three trees the last three seasons if I remember correctly. If they looked like crap or were weak during the flowering phase, I wouldn't be as fixated on trying to figure this out. They really are nice trees and flower like you wouldn't believe.
Just wondered if anyone else had run into this.
