Well, I expect I am mistaken about them coming in true from seed. I
am
a bit of a novice in this field.
Still, it seemed odd to graft a hardy tree onto a not-so-hardy root
stock. The idea that this is to prevent suckering seems reasonable.
I'm near St. Paul, Minnesota.

What is the source of your information, and where are you?
Growing sour cherries on their own roots is apparently not that
easy,
and tissue culture is the favoured way. Evidently some nurseries
prefer
to graft, perhaps to have the whole process under their own
control.

Ernest, grafted trees from commercial sources would probably be
grafted
on Mazzard or Mahaleb. If I remember rightly you are in a
particularly
cold area of northern Minnesota. I would expect your temperatures
to
damage (in a warm winter unless with heavy snow cover) or kill
either
Mazzard or Mahaleb. Mahaleb is fussy about good drainage, likes a
coarse
subsoil. Any hardy rootstock readily available cheap to a
comercial
nursery is likely to suffer from compatibility problems. The only
rootstock I can think of that *might* suit is Prunus X
Dropmoreana,
Frank Skinner's creation. Forty years ago East Malling did some
work
with it as a stock for sweet cherries, and from what I recall
reading,
some clones of it were compatible with sweets and some were not.
If your sources were what I would consider fully competent and
honourable, they would have told you what rootstock they were
using -
unless maybe they were afraid their competition would find out
about it.
This kind of competitive pressure is one of the curses of the
nursry
business. It's extremely hard to know if your supplier is
understandably
secretive, or crooked or irresponsible.

"Before" means before I buried grafts. I was not doing a

study. I was just trying to get trees to live through winters.
I
bought trees from several sources. Local and mail-order. It is
possible burying graft is just protecting graft from winter
cold.
This fall I will probe around buried trunks to see if roots have
grown from Evans trunks. I'll look up Evans own-root sources
and let
you know.

Hello Ernest;
I am interested in your Evans story. The trees that you buried
the
graft union were better 'than before'. What does 'than before'
mean?
Did you plant some at the same time from the same batch without
burying the graft? Same plant source? This is a decent finding
on
your part. Please elaborate. Also, who is the 'own root' Evans
cherry
tree source?
Murph
