I had a potted Pawpaw grow for about 30 years and got several crops (SW Iowa
zone 5).  We had a test winter 2 years ago and most of the tree died.  I now
have to trim back the suckers every year and try to figure what to do with
the remainder of the tree.   Judson L. Frisk

Lucky,

Thanks for your input, I would like to hear if others have had the same
experience. It is quite common for a grafted tree to abort the graft the
year of planting if it comes under stress. I've not heard reports of this
following survival of the 1st year. This may be problematic with pawpaws and
may be involved with the pawpaws dislike for being transplanted.

In thinking about personal experience. I've only planted 3 grafted potted
pawpaws and none of them survived the past 2 years. One that did survive
after the graft failed died the 3rd year. But my experience with only 3
instances isn't enough to draw a conclusion. I believe it was partially my
fault as I may not have cared for them sufficiently. We need to hear from
more planters of grafted potted pawpaws.

About 5 years ago I planted 33 pawpaw seedlings from the IDNR nursery.  
I also have a wild population and took the tractor back and brought in dirt
from those root systems in an attempt to bring in the Mycorrhizae fungi
specific to a Asimina and back filled the holes of every other one with this
soil. I do have a water wagon that I can hall 200 gallons at a time and
spray onto the ground, simulating rain. I had also applied pelletized sulfur
to the ground and tilled in before planting. They were planted in well dug
holes, not chunked in. (Lucky, not trying to put your method down as it's
difficult not to do much else when planting potted pawpaws.)  After planting
when active growth had begun which is when I normally graft trees I grafted
all of them using the Omega or saddle graft. Of the 33, none of the grafts
survived past the 1st year and only 3 of the under stock survived. It's hell
a be a total failure, and after all that work of planting those 33!
