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.

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?
