Tony,
All those apricot grafts were grafted on this wild plum tree 8 years ago?
If these grafts are 8 years old, they shuold be considered compatible, right? My grafts usually show signs of incompatible after 2-3 years.
Yes. I am sure they are compatible by now. I will buy more of this wild plum seedlings next year to have several Orangered and Golden Sweet grafts to them.

Thanks, Tony.
@Barkslip, I hope your are correct that Tony trees are prunus americana. Hopefully, by next year, I could graft apricots on my prunus americana, too.

I asked them years ago, they are Prunus americana.

So, it looks like on Tony’s case, it works with apricots.
I’m going to graft apricots on them now. I’m also going to bench graft apricots on some I have from last year very soon.

anyone able to confirm Americana will work for Euro plums as well as Japanese?
I do wonder w the apricots if there is some variability in acceptance–I suspect prunus Americana covers a pretty broad genetic pool and it may be entirely possible Purvis tried and failed repeatedly, but with seedlings sourced out of a different state that were genetically unique enough for an incompatibility Tony is not experiencing…
Bob,
You can read this recent thread on my multi grafted plum tree on this wild plum seedling. I grafted the Flavor Supreme first then 3 years later that I added more pluots, Japanese plums, and Euro plums on top of the FS.
Tony
Tony, thats cool and no disrespect at all, you do some awesome work, but i did see that–in your case you had a pluot (flav supreme) interstem, if I read correctly. Which is also interesting, i wasn’t sure japanese and euro plums would play nice together, but i was wondering if anyone had experience w a direct graft of euro onto americana—anyone?

I don’t think they would work together.

Why don’t you try Krymsk 1? I have a few going and i’m liking it so far. Have a number of grafts on them. It is very dwarfing though.
my biggest reason is I can dig all the wild plum rootstock I like. The cheapskate in me has great difficulty paying $30 for a dozen rootstock, then $20+ to ship them…
that said I do have mariana or myro suckers coming up in my nursery bed as well…
What about grafting K1 onto your prunus americana…then grafting euro onto that?
then I could probably just use santa rosa, or a pluot, or something else at that point as my interstem without buying K1.
I had a K1 before and was deeply unimpressed with the vigor, I am not a fan of “dwarf enough that I have to babysit it when there’s no rain for a week and I have to stake to make up for the lack of roots” trees, which is why I don’t have any apples on B9 either…I certainly don’t have a problem with dwarf rootstock, it just isn’t a great match for my general level of neglect… Not sure how K1 would behave as an interstem, but I also don’t want a 4-foot tree able to support like a dozen plums
lol… yeah they are dwarfing.
In my opinion…just from what i’ve grown out from seed…pluot seedlings are the most aggressive/fasting growing of the bunch. I grafted pluot onto my cot a few years back an it almost took over the tree. The branch was massive…i ended up sawing it back to almost nothing.
I have 1 p americana and i’m not super impressed by it’s growth. I also think the wood is very weak. I’ve had branches break a few times. If it dies for some reason i won’t replace it. There are a ton of wild ones growing right near my house and they are more a shrub then a tree. I do think they help with my pollination.
If i can figure out how to multiply my k86 that would probably be a good one (best). It is a fast grower and should work with a variety of plums/cots/peaches.etc… I’ll be interested in seeing if it handled -30F.
It has been demonstrated that graft compatibility between different species may be restricted to specific cultivars of each of species such as in the case of Adara plum as a rootstock for cherries, peaches and apricots.
Perhaps @tonyOmahaz5 just won the genetic lottery by discovering a rare genetic freak that is inter-species graft compatible with the cultivars that he has grafted to it.

I have an 9 year old Opal (euro plum) on p americana, doing quite well, and have grafted several other euro varieties onto p am, though they are not as old. It seems likely that some cultivars of euro plum are more compatible with p am than others. P am. has an advantage of cold hardiness over most other options. For me, its a matter of digging out suckers in my plum patch, they a are free resource for me.

Here is my other 8 years old P. Americana rootstock with Prune 707. Byron gold, Ruby Queen, Bavay’s Green Gage, Emerald’s drop pluot grafted on it without any interstem. So after 8 yrs I would say it is compatible.

My two p. americana are still very small. This is their 3rd year in ground. They got some urea this year. I’ll see if doping them will work 
Are you able to estimate how much fruit you get off of your P Americana/Euro plum/apricot trees?
I thinned them every 4 inches per fruit to get a decent size fruit.
