[nafex] Re: sandwiching, Ultra Hardy Peaches
My recollection from Percy Wright's article in the Pomona is that
Percy's uncle (who did the test) in B.C. used a prairie bred
cherryplum, a Prunus besseyi/Prunus salicina hybrid, grafted in the
top of a peach tree for extra hardiness.
I think it might have been a Sapa or Sapalta but my memory peters out
about there.
I have been told that NAFEX pioneer Fred Ashworth in northern New
York State (St. Lawrence County) used to bind the branches of small
peach trees to the vertical and drop old tires around them for winter
shelter. I don't recall but would guess that he closed off the top of
this cylinder as well.
