What kind of damage do you guys think this is?

A lot of little holes on some leaves, along with the edges eaten away on some others. Also on some leaves, there's these little white/gray/brown spots.

May be 2 separate issues? The eaten bits looks like insect damage and the colored spots look like something else, but don't know enough to be sure.

Most of the new spring growth has already started to harden off and deepen in color. I feel like maybe I could have waited a bit longer to work on it, but I gotta take advantage of the days when I have time. It exploded with growth again this spring and needed a lot of cutting back.

I really don't have any experience with this phase of development -- some branches I want to really thicken to help the transition from the thick trunks I cut 2 seasons ago, and in other areas it almost looks like the thickness is where I want it and need to start working on secondary and tertiary branches. I noticed some areas that were getting really shaded out and starting to die, so I tried to cut back harder on top, and cut off every other leaf to let more air and light in to the interior.

These are the areas where I need to really thicken the new leader to help the transition.

In that spot, it's almost like a secondary trunk I'm trying to develop, I don't like the single trunk style on deciduous, and am trying really hard to have another thick trunk here too.

This is on the back side. That thick new leader I let run and is about 4' tall probably. I'm just propping it up and trying to get it as thick as possible to help smooth out that transition.

This is a little branch, but I think important because of its location on the back. It was getting shaded out because of all the foliage above it.

This section here up near the top, I originally was thinking of cutting that knob off to help transition to the new leader on the front.

But then I was looking at this on the back and wondering if I should cut above these 2 medium branches here as the start of the new apex. It would shorten the tree a bit and provide a nice split into 2 leaders, which may improve the transition into the apex? I really have no clue as I have never done this before. :rolleyes: It's hard to imagine what cuts now will develop into 2 or 3 years down the road.

This is the current front nebari, where I'd like to perform maybe 2 root grafts here?

And then on the back side, possibly 3 root grafts here.

Here's a shot after I thinned everything out.
20190424154641_779A8227.JPG

This is a main branch coming off the left side, so I want to thicken it a bit more, but I just don't know if I should just let it grow? Or cut back to 2 leaf pairs? I wired a little movement into it, guessing I will probably cut back to something eventually:?

Found some lady bugs eggs under one leaf too!

I cannot believe it's been another year. Another year with not much work done at all on this tree. At least it gave me more time to look at the tree and think about some possibilities. Right now I'm leaning towards air layering off this whole top section above the red line.

PSX_20200425_233812.jpg

It's got nice branching, but it's just too high up on the tree. Once that is layered off, then I might air layer off the next section down, or just cut it, which would be above this line.

PSX_20200425_233838.jpg

That would get rid of the thickest parts high on the tree and divide the main trunk into 2 smaller trunks which will help taper.

Also playing around with another side for the front, which would be somewhere around here. I got some new growth down low on the left side, which is great. There's a patch of dead tissue on the right side, so won't have any branches there, but the rear branch be able to develop and fill in some of that negative space. We shall see.

And also still want to perform a bunch of root grafts next spring when I repot it.

Thank you for the encouragement @j evans and @kobusbonsainut !

I noticed these white edges on the leaves, any one know what this could be from? I didn't repot it this year. I got an air layer I will separate soon and those leaves are affected too.
