Where can I grow pawpaws?

Pawpaws are a temperate tree that can be grown in USDA zones 5-8. Of course, this is not set in stone, however outside of these zones growing becomes experimental. Be sure to have a soil ph of 4.5 to 7 as well as good drainage, adequate moisture, and fertile soil. See maps above in the gallery of the Native Range of Asimina triloba, and of the USDA Hardiness Zones. It is rule of thumb that plants can be moved 100 miles north of the native range and still do fine.
