So I have been doing a lot of research on rootstock and have found a few that I like. My favorite so far is the M111 will do 65%-80% I know it will do well with peaches but hasn't said much else. I'm looking to be able to graft peaches, nectarines, apricots, plums, apples, pears, and cherries (there are more but forgetting them at the moment). So my question for everyone is this... is there such a thing as a universal rootstock, or am I going to have to find a compatible rootstock for every type of plant?

There are groups of fruits that are related.  Apples and quinces, peaches and nectarines, etc.  Only compatible species can be grafted.  M111 is an apple rootstock.

The details are pretty complicated.  But there is no universal rootstock.

So what kind of rootstock would you recommend for peaches, pawpaws, cherries, and plums?

If it were me, I would ask your question on growingfruit.org.  This is a forum that focuses on figs.  It's ok to ask such question but you should precede the title of the post with "OT".  When I clicked on your post I thought you were asking about fig rootstocks.

Hey Nic,

it depends on how much space you have available. Since you like the M111 for apples, I guess you have some space planned for the trees.
For:

• Plums: Saint Julian A
• Pears: Quince A
• Cherry: Colt (but this is know to have some issues with diseases and is not widely used in Europe)

My pears are on OHxF 87 and 97, which are standard or close; plums on Myroloban, standard.

Thank you so much for the info guys. I greatly appreciate it. It's truly a blessing to be able to learn from fellow enthusiasts
