My grandpappy told me that if you want a good crop of pawpaws you have to hang a dead cat in the tree. I think dead cats were in greater supply back in his day.
Fascinating flowers for a tree though. Red meat color and odor only a fly could love.
For anyone that’s close, go to the upcoming Ohio Pawpaw festival! https://ohiopawpawfest.com/
Yeah I've wondered about just really nasty ass stinky fresh manure around the base of each tree. That would attract flies.
Probably a flush of nitrogen at exactly the wrong time tho. Most plants respond to that by pushing excess green growth instead of flowering and fruit set.
