here is the june update.
the 3 way(susquehanna/potomac/shenandoah) is looking solid:
the 5 way(jerrys big girl/potomac/mammoth x/susquehanna/chappell) has been slow on the left side, the side opposite of the damage to its trunk, but the last scion(jerrys big girl) pushed a little green from a bud so hopefully it will make it 
i accidentally broke the top shoot off the center scion(mammoth x) and it grew another from the node very quickly. most of my pawpaw grafts have been with 2 buds.
so ya it seems that all grafts have taken. ill report back towards the end of summer/fall.
