I'm about 200 miles north of the native range of pawpaws, I was
thinking 0% success with grafted pawpaws was a hardiness issue, but
maybe there is something else going on.  A few of my grated trees that
died had done well in pots for a couple years and were maybe 1/2" or
more caliper.  Everyone has winterkilled, scion and rootstock.
