In looking for more info about pawpaws, I came across https://attra.ncat.org/wp-content/uploads/2019/05/pawpaw.pdf which I found informative and think others here might like:

"This publication is intended as an overview of pawpaw production, including overall culture, pests, harvest, postharvest handling, marketing, and research that seeks to advance the pawpaw’s potential for commercial development"
