Everyone writes about how pollination can be a problem with paw paws, because insects don't seem to be interested in the flowers. That seems to be a fact, because I watched some this year, and even though I saw insects on the nearby apples, I didn't see any near the paw paws. But even the tree in my yard that is 100 yards from another paw paw is loaded this time. So, perhaps the wind and weather conditions were just really good this time. The one above is a grafted paw paw that is believed to be self pollinating.
I have one tree at the farm I'm anxious to check Saturday. I saw it covered with flowers the other day. All of the others nearby are too small to make flowers, and I don't know of another paw paw within a mile. if that one is also loaded with fruit, I'm going to start wondering about things.
I've read where the old timers rubbed bacon grease on their trees to draw insects. Never tried that but it sounds reasonable.
