Acer palmatum beni tsukasa (from cutting)

yes, first of all = create large nebari + large trunk with sacrifice branches + heavy fertilisation.
Secondly = thread graft definitive branches + less fertilisation (lower inter-nodes)


PS : IMO in order to close the scars quicker, it is important to keep at least 1 sacrifice branche to keep a good growth on the tree and then a good healing speed. If you cut all the sacrifice branches in just 1 time, and if you start to pinch your tree, the scars will close very very slowly because the tree will grow very slowly too. So, IMO, the best is to keep the last sacrifice branche at the back of the tree, because the last scar to close will not be visible on the front.

P.S Don't be afraid of going deep in to the trunk, this things, may close better if the callus grow to the inside

Ebihara's large cuts are flat or convex so i'm not sure ->

If the cut is flat, the trunk must thicken more to cover it, if it is convex, even more....or your will have a bump. That not bad if it is what you want....all depends in your POV.


In this shindeshojo, I made a concave cut years ago..


A little more of fattening


And today, only a different color in the bark remind us that there were a cut

Fron the side.


Good luck!!


Cheers.

your experience is interesting and your pics show me that the trunk tend to swallow the scar bump.. that is a good news for me as i have "scar bumps" every time, whatever the type of cut (concave of flat)

Don't be shy and go inside the trunk. Even large wound will be sealed completly if you have enough patience. Is only a matter of time.

Take a look to this Peter's tree. It was worked with an axe in the early sixtys



And in 2020 looked like this, no mark of the wound at all!!
