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.

Dan, what you have heard does not agree with what I have heard from a 
very well-informed person, which is that Evans does not come true from 
seed and that Evans seedlings are not even cold-hardy at Edmonton. See

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.

Why would one bother to graft Evans since it it is hearty on it's own 
roots and supposedly grows true from seed?...

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 research
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?
