Trident Pruning 2

This one has been growing out since 2009(?).  


The first trunk chop was done in 2013, and is about 75% healed:


I will breathe a sigh of relief when that bottom chop is closed; exposed chops tend to rot, which makes them nearly impossible to close, so it’s a race against time.  I reapply sealant several times a year to keep water out.

A bit of a haircut, removing the excessively thick branches, and keeping the sacrifice branch intact.


The upper section of trunk doesn’t translate well on 2D photos.  It moves forward, creating the illusion of a bulge.  Maybe it will be easier to photograph when it’s up on a bench.  For now, it’s on the ground, in an Anderson flat, and the roots have long-since escaped out the bottom and into the ground.  I’ll have to “collect” it when it’s time to repot!

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:

Nice taper:

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.
