Grafting Greengage Plums

Hello, I am looking for some advice on grafting greengages. I have Myrobalan 29C and Marianna 2624 rootstocks but am hearing mixed things about compatibility of these roots with gages. Has anyone ever grafted gages on either of these?

One Green World supposedly offers a greengage on Marianna but from what little information is out there, it sounds like that combination is likely to have delayed compatibility issues.

Could an interstem be a good option here? I have a few other varieties of European plum scions that I could use for that (Imperial Epineuse, Opal, Seneca).

I have Bavay’s Green Gage, and Reine Claude Doree both on Marianna for 5 years with no issues so far. Trees of Antiquity sells their Gage’s on Marianna as well.

Interesting, do you know if they use an interstem or if your trees have an interstem?

To my knowledge TOA does not use interstems. There is no obvious interstem by looking at the tree but I can’t say for certain. I guess it could blend really well.

My own grafts on Marianna 2624 did not have an interstem but I gave those trees away to fruit friends. I’ve heard no reports of graft failures.

I have a Mt. Royal .. started it in 2018… best I remember it was a Dave Wilson tree. No idea about the rootstock.

You might be able to find those details on his DWN site.

I added 2 grafts of Green Gage to it last year… they grew well and bloomed this year.

My Mt Royal has set lots of fruit.. hope they ripen. If so this will be my first EU Plums.

Lots of good info on this Wiki if you haven’t seen it.

I may just go for it then and graft them straight on Marianna, thanks

Finally got blossoms on the Mt Royal? Nice!

Mine looks like it’s about to as well, its fifth spring in my yard.

I’ve had a greengage on marianna 2624 (from either OGW or Raintree) for 15 years, it is precocious and seems healthy. Only downside is suckering and it is probably taller than i would like.

@slartibartfast… Mt Royal is supposed to be self pollinating.. but mine bloomed 3 years and set no fruit.. or what it did set it later dropped.

The Green Gage grafts I added bloomed perfectly with Mt Royal. I figure a little cross pollination might help.

Good luck with yours !!!

I have a green gage on myrobalan, also a DW tree. Entering year 2. No issues so far.

I ended up contacting Trees of Antiquity and they said they have been grafting gages directly to Marianna without an interstem for 35 years and have never had an issue with compatibility

Interesting. I tried green gage on myro last year twice and both failed.

Looks like Cummins sells it on myro too.

@TNHunter Good afternoon sir. Do you by chance know if these are fruiting buds on this green gage? Ive only ever seen EU fruiting spurs on a stanley in real life and there were always 4 or more together in a bunch, so thats why im questioning the buds here.

@Bogovich… I am no expert on EU Plums but I think you are right that those will develop into something like fruiting spurs.

I remember several years ago when my Mt Royal first started developing those. Now the scaffold branches on my Mt Royal are covered in shorter growths like that.. one every 2 3 4 inches especially on the lower half of scaffolds.

They do bloom and set fruit.

They will get taller.. a few inches to 8 or 10 or more inches. I prune the taller ones back some each spring.

Several of mine have fruit on now.

Good Luck to you !

@TNHunter very cool thank you for the info.
I try to cut the water sprouts back to 1 shoot as directed by this gentleman below. (I did cut some too early before they became woody at the bottom and they died off)

This water sprout was cut twice in 1 season and now i think its producing singular fruiting buds.

Heres another

I have Mt. Royal and did get a few plums last year. It is a pretty hardy plum and mine is on Canadian plum and is about 6 years old.
