You talk about apricots to European plum do you think this also applies to domestic plums?

If your talking about me Ubro, then sorry for not being precise. I think I was in my 3rd paragraph meaning "hardy domestica plum" with the spelling correction, same as hexaploid european plum or a hexaploid green gage if any of the guages have been noted as apricot rootstocks before.

To be exact, this is what I received from the Government into Alaska. I bud grafted it to several branches at UAF to follow through with the above side-by-side points. If it breeds with the Gabe-C or any other future apricot such as 'sunrise' into Alaska at some future time, even better.

The reason I think a little favoritism of domestica (european) plum is from information by others that have performed such crosses observe orange apricot roots. The other thing are the flower buds are 3 buds wide, similar to apricot and peach.

sorry alcan it was I who was not clear. I meant is there any long term success of grafting apricot to our wild plum prunus nigra. I have been grafting apricots onto both prunus nigra and prunus americana. Having said that, I am sure the rootstock are just seedlings of "I don't know what". I say this because each one, when it suckers, seems to be a little different from the other. I was concerned that my efforts are in vain.

I have not seen to much evidence supporting that any plum roots would produce abundant loads of apricots.

I have seen a couple trees that were twenty years old growing decent crops of both euro plums and apricots. Besides this from my experience the plum will only support the apricot and grow it but fruiting will be very minimal. grafting plums to apricots almost nothing ever produces fruit for me but the grafts grow fine? Reading online articles from southern growers in California they don’t recommend any sort of mixing plums to apricots to peaches ect... as they won’t reliably produce

Well..my Sunrise apricot is grafted to a wild plum for over 15 years and doing good. I've just started this year the other way around, plum to apricot, time will tell...

Oh...Capilano apricot I have also grafted to wild plum and looking good. I was thinking to try Mustang root stock, so Matt, our Casino is on Mustang right? If so...don't see much growth..at least less the wild plums. Think yours died. Do you think Mustang is hardy enough for us?

I have lots of cherry plum seedlings coming from the Gypsy plum, [2 years old] for sale, fall or next spring, a bunch of 10 @ $100 also Capilano apricot seedlings.

Thanks for the reply, I am not so concerned with abundant fruit, I just would like them to survive and produce some. I am lucky and have lots of space and in my zone I have resigned myself to fruits trees not being highly productive.

I did plant The Capilano, Gabe A and Westcot (grafted onto plum seedlings) in my unheated greenhouse to see if the increased protection from the harsh winters may result in better bud survivability.

Gabe states this

" Graft hardy apricots onto sandcherry, but not onto nanking cherry or plum (some salicinas excepted), unless you want to hold the scion for only a couple of seasons or less before final grafting onto a sandcherry. Apricots on sandcherry need to be staked. If you use sandcherry as an interstem, apricots will usually do well on plums and nanking cherries."

I say try using Sap.07-01, that has apricot and sand plum in the genotype, or sand plum (per Gabe) as the interstem.

I know in Fairbanks Alaska Clair had apricots and no fruit. But Clair is gone now as well his apricots. Does anybody know if his were grafted 'mistakenly' to American plum or not? (maybe I need to find the family)

I would not buy another apricot tree grafted to mustang . Had a few of them die now due to this issue. Years ago when nurseries here didn’t use mustang or it wasn’t popular I bought my first apricots and they are still alive and produced lots of fruits. We have had many amazing seasons in a row here like five years of good weather besides last . I don’t think it was weather I think plums or on most plums won’t work. I even have issues with mustang roots for plums. Best roots for my area for me are maraiana 26-24 and myro.

I made a mistake on my last post about heaving Sap. 07-01 seedlings coming, have edited... they're cherry plum seedlings from my Gypsy plums, the 07-01 seeds I just put in last fall, only very few came up, think most died from not heaving snow cover.

Matt...I know you post sometimes here, you might want to add your comment about Mustanghere

Konrad I’m not even close to being at the same level as you. My experience with this is probably 25-30 years behind you and this subject is probably nothing new to you. I maybe expecting a bit to much in our climate but somebody will crack the code one day and develop some that produce

I don’t mean to bash the mustang rootstock I know it was developed by Jeffries nursery .

I re-read this thread so what is the possibility of root grafting apricot onto plum roots, and when planted allowing the apricot to form it's own roots. Is it that the apricot roots are not winter hardy or is it a disease issue that requires apricots to be grafted.

I’m not sure either . I know that Manchuria apricots make good roots as per many experts online. They also use m604 as roots in ontario As it’s parentage is Manchurian.

I was re-reading this because I want to purchase a couple apricot trees this year but they are on mustang roots. my plum trees don’t even grow long here on mustang and all 5 have started to develop kanker and health decline. three black ice ,Toka and brookRed. All of my other plums are primarily euro and don’t have such issues.

this could be a question for Konrad or Alcan than ? say if I bought a debbies gold apricot grafted to mustang roots and planted it below the graft like would the debbies gold shoot out roots and start growing on its own root system. Also would the mustang roots die off if I planted it below the graft union or would they continue to grow and the apricot grow it’s own ?

I was just considering to root graft a few extra scions that I have onto plum roots rather than the whole plum rootstock. Apparently, the small plum root holds and feeds the scion until it forms its' own root system. I did google it and watched commercial propagation done this way and it looks pretty doable if you are used to grafting anyway.

So one would just dig up a root about the thickness of the scion and simply graft like this ?

Yes...it's just closer to the roots called root grafting, or you can bury the scion...which I've done but have yet to find out if rooted. I've done a sprouts sunshine on Nanking roots, dug it up and planted deeper the following year..grew good for about 5 years and had plums until Voles destroyed it...shot up again from the base last year which tells me something worked out ....a vole prove tree lol. I've planted some others deeper on plums but never rooted...died about 3 years later from the wind whipping the tree around damaging the roots below. Stem above wasn't anchored, making the hole/ground about 10 time the size of the stem from the wind...took stake off too soon...might have never worked anyway, some are just hard to root I find.

Maybe this link can help. Although written for California, what apricots can be grafted afa rootstock is conerned should be pretty uniform regardless of location.

Japanese plums are actually closely related to apricots rather than European plum.

If you want to graft European plum to another stone fruit tree, you may have more success with a myrobalan plum interstem. (In case you have trouble finding one, they are a common ornamental tree, in fact where I am the streets are lined with them)

is there any certain length of interstem that needs to be used ?

Are you sure apricots will grow on myrobalan plums ? Is this not just a mix of cherry x plum hybrid ?

I read a report of a small commercial orchard that was successfully able to convert peach trees to grow cherries on using a myrobalan interstem. Peach and cherry are probably the most incompatible (I can't think of the proper way to phrase it right now) of the stone fruits, so if it would work between those two it would very likely work for others.

Aprium or Plumcot varieties may also work as an interstem, I would think.

I don't think the exact interstem length is that important. Probably anywhere between 2 to 5 inches should be fine.

I think the length of interstem is important.

Is this the report you’ve read ? I read this a while ago and had no luck finding adara interstem. They didn’t graft onto a peach directly as I doubt a myro plum grafted to a peach would take .In this report the roots were “citation“ which are half peach half jap plum. Which are a very common peach rootstock .

https://www.tandfonline.com/doi/abs/10.1080/00221589.1993.11516403

Yes, that was the article.

The article says " Adara (Prunus cerasifera) " and Prunus cerasifera is myrobalan plum.

In the city where I am the streets are lined with them and they're in bloom right now, to say it's a widely planted tree here is an understatement.

I don't know if there's something about Adara that makes it different from regular Prunus cerasifera when it comes to ancestry and graft compatibility.

It’s not grafted to a peach In this article though. It’s grafted to a citation rootstock which is half Japanese plum which is probably why it worked.

Of course there is a difference between adara and myrobalan plums

Could almost guarantee some of those myrobalan plums near your house are all different from each other as likely seeds that spread naturally. Some would accept other prunus grafts but non alike

The most likely name you should want for cultivating apricot on that's available in the prairies is "muckle plum". It's going to be superior to any myrobalan plum in the way that muckle is 50% of the less hardy myrobalan and 50% of the more hardy bessyi plum. Also the bessyi plum (also known as the prairie sand cherry) is proven more compatable for grafting with apricot than myro plum.

Down here in Washington I think the common name of the muckle plum is 'newport', while in Canada I forget which. Somebody google for muckle plum and "Skinner" and come up with a name. I'm sure bylands has it and Skinner is the last name of the decessed breeder who came up with the first of the type. It has the same ornamental red leaves from the ornamental kind of myrobalan, not the green leaf kind sich as 'adara'.

I have to say that I know when I had enough of the gardenweb annoyances. No more garden-web anymore. Sorry guys. I'm alcan_nw and garden-web "wormed" into my cellphone browser and registered gmail to plant my real name. Good Luck!!

My.mistake. I mean prunus cistena by Dr. N.E.Hansen, not muckle plum by Skinner.

A bit of advice is find a safer place than this to hang out. This place is "wormy". So is my comcast.net email account that I have had for 20 years bad. I pay, they keep cutting me junk and tome to move to safer places. alcan_NW

Alcan I only use apple devices they don’t get hacked. Join the Facebook group it’s a bit busy and hard to follow I liked gardenweb a lot better than houzz. If only somebody could startup another forum that runs as I notice the glitchyness of this site too it’s a pain in butt to post on here now.

They have newport plum here and I’ve seen muckel plum. I have apricots grafted to sand cherry thats what my trees are on and they produce fruit. I only know because the sucker it shot out was distinctively a sand cherry.

I was was hoping somebody with a grafting combination of apricot to euro plum could share the experiences of what types worked. I have apricots growing on my Italian plums but on greengage would not take or survive winter ok. I have a couple flowers on a three year old m604 graft on my Italian plum right now. Pretty excited as I plan on removing all my hybrid plums and planting European plums only as they are much more suitable for Calgary.

Hi guys, I am working with fruit trees in northern Mongolia(Zone2/3). I have been following the various forums on plums on this site for the past couple of years and I have really enjoyed the comments and discussion. Are there other forums like this and are you moving off of this forum.
