Re: [nafex] Pawpaw question and observation

Robert from the Men's and Women's Garden Club of Minneapolis has had great luck growing pawpaws from seed he got from Oikos.

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.

I tried at my most recent site.  At this site, I've had
100% failure, though understocks do great.  The most
annoying failure was a Shennandoah tree that grew well above
the graft for two years, then croaked this Spring.
