Hi Dennis,
Thanks for the ideas. I am thinking of having a bamboo cane to train the scion to, like shown by Dave, here. But, that won’t really support as low as the graft, so I think your idea of a separate splint for just the bottom part may do the trick. I was concerned that tying to the larger cane and then packing the soil would be an issue to the graft, but done your way, that would be less of an issue, so thanks on the idea. What’s a good material to use to bond the scion and new growth to the canes, that won’t abrade the new growth?
Now, all this said, I’m pretty busy at the moment with rebuilding the house, and thinking putting in containers, at least until fall, may buy me some time, as preparing the ground and building the structure may take some time.
