Paw Paw Trees

Here are the 2 containerized Paw Paw trees I bought yesterday at Portland Nursery. When I walked past them I thought No! Impossible! They are the named varieties, Sunflower and NC-1. Based on my readings, the roots are delicate. The trees are best planted while in growth, not dormant. It is best to shade them for the first 1 to 2 years.   I'll have to identify a spot, clear it, enrich it with compost, and plant them. Not sue if I'll do that now or just keep them in the containers and plant next Spring.
