Edible Landscaping Pawpaw

My Edible Landscaping asimina triloba had a rough start. It began to grow, then the new growth turned brown/black, dried, and died. I think the plant may have been getting too much sun. I could be that the plant was experiencing shock from being shipped and planted outside when it was originally in an indoor greenhouse. Regardless, I think the plant is rallying now. She has began to grow again.
