That's great.I have a Sunflower that's about two that started to fruit by me using it's own pollen,but they fell off.
I've read they get fairly fragrant when ripe and will drop and also be somewhat soft to the touch. Brady

I didn't pollinate the pawpaw. I planted two trees close to each other so maybe that helped with pollination. The second year the flowers almost formed fruit but fell of afterward. I only tasted the pawpaw once. I hope mine will taste good.

How large was you tree when you planted it? I planted mine last fall when they were 18 inches. Now they are about 2 feet.

Mine were grafted trees. They were 12-15 inches. My trees are still short, I think maybe 6-7 ft now.
