Here’s one I’ve been working on for about 12 years, maybe longer. It has a fat little base, and wagon-wheel nebari, and is in serious need of refinement.
Last year, I dug it up and potted it for the first time in 6-7 years. It has a bad chop scar on the back that is slow to close, and was impossible to work on while in the ground.
I defoliated it to get a look at the branch development:
And to give the grafted branch a little sunshine. While it was leafless, I scraped the cambium around the chop and suspected it might just be rotting under that cut paste. Digging a little with a gouge confirmed that suspicion:
So I removed what I could, and then used a Foredom rotary tool to remove as much rotted, soft wood as possible, and got it back to hard wood:
Then, I treated the inside with PC Petrifier, a water-based wood preservative.
Allowed it to soak in and dry overnight, then over the course of a few days, filled the hole with interior/exterior wood filler.
A week later I had a few minutes to smooth out the edges of the wood filler, and clean up some of the rough bark:
And one more week later, I was able to wire the grafted branch to move it to the right and add a little wiggle.
Now, three weeks later in mid-August, the branch is setting, and I’ve been reducing the back of the grafted shoot:
I also stripped the lower leaves from the sacrifice branch to keep the sun shining on the final tree:
Soon enough it will be down to the final tree itself:
The graft was separated, unwired, and shortened, and pruned back in late August. Here is where I’m leaving it for the remainder of the growing season:
Next spring, it will be repotted and the nebari will be worked a bit more.
