Thanks, Phil. Your comment reminds me of seeing a nice, big Asian persimmon on Youtube that lost a massive limb because it had so much fruit and got hit by wind. The owners were clearly gardeners, probably busy with other things, and their long-established tree needed help.

I have asked an orchardist about reducing the length of scaffold branches for this reason, but he didn't seem to know what I was talking about. My question on this forum is simple, but it does go to the underling issue of strong structure you mention.

I'll try to attach a photo of the overall tree.

It's most susceptible in the autumn as the fruit are starting to put on some size and the leaves are still attached. The tree is in one of the most sheltered spots on the property but I think it's the turbulence that gets it. As fruit trees go these seem a bit delicate to me...our apples, pears. cherries and plums out in the more exposed orchard get more  wind and suffer a lot less breakage.

All this is to say that having good structure is likely to be important if you get any windy weather during the growing season. Don't let any weak crotches form, and don't let new branches get too long to keep leverage to a minimum.

Not sure, Dennis. But I prefer central leader because it's more familiar and I think it's stronger. Also, in this spot I want some height for a screen. This form may not be quite as ideal for fruit, I realize.

But actually my question would be the same. Is it okay to leave the two headed branches and try to shrink their stem in relation to the branch's new leader and the tree's trunk, or would cutting them off with a heading cut below them be preferable?

If I mentally move that whole branch upright like it's a sapling, the lower heading cut, reducing the branch to the new leader, doesn't seem as major as it does when I think of it as a big branch with a weird structure.

Hello! Today I trimmed this little Saijo persimmon behind my barn. I am letting it develop some low scaffold branches and will select for some higher on the tree. In the first attached photo (overall limb view) see the branch on the left: I want to turn the low, lateral shoot into that branch's leader and ultimately remove the two upright leaders. Note this branch's base, showing it became codominant, almost the size of the tree's leader.

So far, my cuts have just been large heading cuts to the two upright branches, one the former leader and one fighting it for dominance (see closeup photo).

So you might wonder why I didn't just go ahead and take them off, and that is my question. Should I? I am trying to decide. Taking them off now would result in a large, awkward wound, I think. It would be like heading a sapling or majorly cutting it back to the lateral, but don't orchardists do that all the time?

By heading the branches but waiting on cutting the stem, I hope to slow their growth and thereby shrink the trunk-like branch section below them. The idea is to reduce the wound when I take them off. If the headed branches go wild, I can head them again this summer. But will that work is my second question?

Thanks, Dennis. So that IS trunk and I should lift it. I really think now that this tree has been struggling because the lower part of the trunk was planted. And I need to go lift it a bit more tomorrow.

This came from Stark Brothers, though they probably bought it from a grower.

I have a question about what is upper graft wood, and therefore part of the trunk, and what is root on an Asian persimmon. I got this potted by mail order this summer. The grafted sapling's trunk came straight out of the pot, no root flare. Leaves became yellowish, and I gave it some Fertilome Root Stimulator, very low Nitrogen, Phosphorus, and Potash. It had little response, though all other struggling plants have really responded.

THEN I re-potted it in a bigger pot, to grow more till fall. This revealed a buried 3"+ section of much darker wood and then a slight flare and roots. That's the graft wood, I thought. There were no roots coming from the black formerly buried trunk part. I potted it with that black wood out of the ground. The leaves stayed yellowish. I gave it more Fertilome to little effect. The yellow leaves may be a completely separate issue, of course.

Yesterday, I planted this tree out. I split the difference, burying about 1"+ of the dark graft wood, as it seems to me. There were no roots coming from the dark wood, more support for a trunk that got planted too deep. But again, it stayed black and it and the tree did not change after 2+ months above ground.

The picture shows the black trunk base and the clear line between the bottom black part, which I think is the graft, and the lighter brown trunk. I can bring in some more soil if the black should be buried. Or I can lift it if more of the black should be out of the ground. I have written the nursery but have gotten no response yet. Help!
