Steve,
A short experience with Geneva on southern heirlooms:
Two years ago I ordered some Geneva 41 rootstock, hoping to grow some southern heirlooms for what was to be a home orchard high density planting. In speaking with the nursery where I ordered them, I was informed that the Geneva 41 has an incompatibility with many of the southern heirlooms. He wanted to know if they did well. I ordered them anyway and grafted 50 of those G41's in Spring 2013 (and I'll have to recount to be sure) I think I have only 8 or so still living... All those still living are
Vandevere. All the rest of them died for no apparent reason, planted in a nursery bed next to other trees grafted at the same time on M111 and M7 that did fine. Was it virus incompatibility? I'm thinking so. I should have listened and gone with a different rootstock. Lesson learned: listen to the nurseryman.
Now that's not what you asked for but I felt an obligation to bring it up since you grafted onto a Geneva. I hope yours does well. Since I'm pretty new to this I figure it'll be one of those things I needed to learn the hard way. Hopefully it'll help someone else.
