Can I save this Pawpaw?

Picture included if I did this right.

Zone 6, NE Kansas. This Pawpaw tree is about 6 feet tall, and was growing vigorously until this spring. We had a very cold winter, with a late, hard frost in early May. The tree was not leafed out yet when the frost hit. One branch is still alive, with small parts of a couple others.

Can I prune this tree and save it?

(There's another nearby pawpaw of a different variety that was leafed out when the frost hit. It simply dropped its leaves and grew new ones, and is fine.)

What did you use to kill the grass around the tree?

Roundup. It did not hit the tree.

Were any of the stems on your Pawpaw tree green when you applied glyphosate to the grass?

I would prune it back in the fall/winter/spring... Pretty much when it's dormant.... Next I would apply mulch around the tree. An organic mulch, not the rubber stuff that never breaks down.... Then, I would graft on some "super varieties" onto the root stock. You could technically have 2-3 different varieties grafted onto that rootstock.
