Rootstock for cherry/plum hybrid?

Hey everyone,
I was wondering if anyone had any experience grafting scions from the cherry/plum hybrids. does anyone know what rootstock to use for these trees? Plurry and Nadia Cherry plum. I believe plurries are a combo of European plum and cherry and the one variety Nadia is the only one I’ve seen of a Japanese plum crossed with cherry.

By no means do I have any experience with grafting, but I did happen to look into these crosses this week and can point you here: https://www.burntridgenursery.com/Plum-Crosses/products/145/

Hit the little pulldown menu on the different crosses and they show what rootstock they're on. Looks like "citation" and "St. Julian" are the two they use. I'd be growing some if I cared for plums enough to grow them to pollinate the hybrids, which I'm almost surprised are not self fertile.

Thanks, that is actually where I was looking at them to begin with. My budget is low so I was looking to graft and they didn’t have either of those rootstocks for sale and I wasn’t sure if there were any compatibility issues with other plumb rootstock or if they would be compatible on Cherry.

I also saw on https://www.onegreenworld.com/ that there are some of these hybrids that cross pollinate. So if you do not like plums that might be a way to go.

I would try Myrobalam (Prunus cerasifera) rootstock. It produces large size tree. I have it under European and Japanese plums. Two I bought just as a rootstock to check what fruits it will produce. One died, the other is growing well. Burnt Ridge has them for $4.50.

I have successfully grafted a plum onto a peach tree.

If you have easy access to the scions that you wish to graft and aren't in a hurry, I have found that plums grow easily from stones so you could plant some stones from your Pluerry & Nadia plums and graft onto the seedlings for earlier fruiting.

The plum grafts fruited within two years, versus seedling trees that took 5 years to fruit.

I have grown many peaches, apricots and plums from stones to plant in our community garden and if I don't like the taste of the fruit, graft other varieties onto the trees.

The peach seedlings set fruit very quickly.

I’d second the Burnt Ridge Nursery recommendation for many reasons. I would not be surprised if they give you good advice if you email them. Very knowledgable and good people.
