Grafting superdwarfs onto M111

Does anybody have any experience grafting MARK interstems onto M111? I've been spending time at Nick Botner's and have been impressed by the trees on MARK which he has in abundance. What I'd like are MARK features with drought-tolerance, which MARK apparently lacks.

In general, does experience suggest M111 gifts drought tolerance to other dwarf interstems, while maintaining interstem behaviors, or do we end up losing many of the qualities in a melange as awkward as this too-wordy sentence?

Nick, I mounted Mark on standard seedling rootstock to observe how it performs. I have read that one needs 15 inches of interstem to take advantage of maximum properties of the interstem.

I am of the personal belief that it takes that much interstem cambial volume to "condition" the flow of juices and nutrients back and forth. The molecular interpreter if you will. Mark is known for heavy production, and that factor alone could condition the scion to spend time diverting solar energy to fruit rather than shoots, given adequate cambial interstem volume. The more the better in my estimation.

Mine, being only one season old, grew much better than when on their own roots. Too early to tell just yet, but I plan on doing just what you are doing!

I have had really good luck using just M26, or Bud 9 w/o doing the three stage interstem. Can't help but suspect that the M11 will start to throw root suckers like an M7 due to the strong root vigor coming against a restrictive trunk.
What has been the long term results for others who have tried the interstem on M111?
I like my trees on M26 and Bud 9 just fine. The Bud 9 is free standing here, though it is suggested it be staked. It is at least stronger than M9

Very useful, those impressions, thank you. And I must admit to being made slightly nervous about M111 suckering. That rootstock has chutzpah. Yes, I was wondering how flow-down affects rootstock as distinct from flow-up affecting scion.

It would be good to hear from others who have surely gone before, somewhere. Do we ever port questions to NAFEX, or is that akin to going over to the (twilight zone)other side(/twilight zone)? <smile>. Personally, I'm a bit of a digital homey.

I was back at Nick's yesterday, cutting scion for the HOS propagation fair. Lovely time. And yes, Karla's cooking was up to its usual excellence. I brought a few friends along to help. I don't think they were used to a glass of wine at lunchtime. Conversation got quite animated there, for a time! It has been delightful learning about Nick's history. Before moving to Oregon, he homesteaded in Alaska for a couple of decades 50+ miles from the nearest road - the get-away-from-it-all impulse prompted, in part, by his experience as an infantryman in Europe in '45 under Patton. Around his land, I find myself having to keep up with a man in his mid-eighties. Astounding. What an immensely generous-hearted soul he is.

If you want to get Mr. Botner really excited, tell him there is no difference between wild apples and bird-planted seedlings! LOL, it'll cost you some sleep time, but you should be able to get to bed by 3 am or so!!
