I'm not happy with the red flesh apples. They are too small, too sour, even astringent, too hard, and just not very good. That's the bottom two tiers of each of theree espaliers. Too much garden space to waste of something I don't like.
I read some where that lower tiers on espaliers are not as vigorous as uppers. I don't know if that is true. I decided to remove most of those lower tiers, and graft vigorous varieties that I know I like, in their place. So it's an experiment.
I collected scion from the varieties Akane and Jonagold, so far.
This is way more than I will use. It's good to have choices for grafting, and they needed pruning anyway. These are in plastic zipper bags until later winter. I don't like using plastic, but these are washed, re-used bags.
There are three espaliers to re-graft. Not sure about the third choice. Porter is vigorous, and good so maybe that one.
