We had Pawpaw wild where I grew up. They grew alongside redbuds in a truly understory location. They would sprout and grow to fruit stage underneath mature stands of elm, hackberry and hickory. We didn't have maples in my part of Missouri much. They didn't grow much where it was brushy or in a dense thicket, but in open woods where the mature trees were spaced out a bit - they were mostly in shade with a dappled sun effect. We went to the woods to search for Morel mushrooms in the second week in April, and the Pawpaws were blooming with their little brown tulip blossoms, and the redbuds blooms were sharing space with tiny heart shaped leaves at that time of year. Pawpaws didn't grow much more than 8 feet tall - and I never saw one with a large trunk - maybe a 3 inch diameter max. Best of luck with your Pawpaws!
Jill said:You should do well planting there, but you should keep an eye on sufficient water for the first couple of months until the pawpaws become well established. I think once they get a good toe-hold, they will do fine. Best of luck!

Young trees are susceptible to sun damage the first 2 years. To remedy that I planted Kong Sunflowers in the same area I planted 2 trees. These sunflowers grow so tall so fast, they performed an admiral job of shade protection. Being self seeders, the sunflowers returned to fulfill said duty the following year.
