 Anyone have experience growing peach, apricot, cherries on
 Myrobalan roots?

Hi Eric,

I have personally grafted all sorts of combinations that I later found out 
are not recommended; your particular combination I admit to having no actual 
experience with.  But I did find and copy this information from the Ontario 
Government Ministry of Agriculture's Apricot Fact Sheet:

Myrobalan Plum Seedling — These are not normally recommended for use with 
apricots for several reasons. The graft union between apricot and myrobalan 
plum (Prunus cerasifera) is weak and may break in a strong wind. Slow decline 
of apricot trees on Myrobalan seedling rootstock has also been reported. 
Apricot trees on Myrobalan seedling normally come into bearing later than 
trees on apricot seedling. Myrobalan seedling rootstock is only recommended 
for areas where drainage is imperfect and apricot seedling will not perform 
well.

What have you used up to this point for rootstocks to graft Peaches, Apricots 
and Cherries too?  I'm looking for a suitable Northern hardy rootstock for 
grafting pit fruits as well.  The only thing I can come up with is Evan's 
cherry seedlings as the pits are free for me.

The Ontario government's online Fact Sheets are so full of varietal 
information as well as rootstock recommendations that I have downloaded all 
their fruit tree fact sheets to my desktop for easy reference.  They don't 
mention Myrobalan rootstocks in the cherry and peach/nectarine sheets.
