The center will not work, no cambium,.. this makes me wonder if you get the cambium in scion lined up with stock?..Take the best growing scion of your graft and get rid of the rest, this will be you central leader.
You need to support the graft with something, otherwise the wind can break it off, I graft on smaller wood with one scion, in one season it can grow over, no need of support.

I would think the tape would prevent the wind from blowing them out if that's vinyl electric tape. I agree that you should chose a singe leader and develop your scaffolds from it to assure a strong union of scaffold branches.

No worries for braking it off now, only when the buds grown out
later in season, a strong gust of wind can break it off.

I used bark grafts and I'm confident that the grafts will take. I just didn't know if I should try to achieve a set of scaffolds from the start or not. But I will focus on choosing a strong central leader and see how things take shape.

I should have put something in the pic for scale. The diameter of the Yates "interstem" (I guess is what you'd call it) is about 1 1/8" and each of the three pieces of scion wood is much much smaller, at ~1/8". The grafts are about waist-high on a supported trunk grafted onto bud9.

Thanks for looking.

Sure...the graft's look good, please show us your progress and
we can help later.

What I have done is,..cut back or top off and let waterspout to form and graft on these, sure, you must wait one sason. If you don't want to wait, use a smaller side branch and graft about a foot out from the trunk, then, bend it upward, tie to your main trunk which was cut back a bit. This side branch will be your new leader. Cut the remaining trunk the next season at the level of your new leader.

This was the result, [2 variety] on bottom, [no fruit] is a early apple which I used a smaller side branch method, the top is a late season apple, if it was in reverse, some falling apples could damage the late apples.

Your pics are always so good.

Thanks...I was out pruning today and took a picture from this tree, dormant, you can see, center bottom only a little of a bump where the center branch was cut off.....perhaps around 8 years ago?
