PT's Coast Redwood #1

[PowerTap]

Starting a progression thread / asking some advice on progression.

I bought this coast redwood from Jonsteen Trees as a starter two years ago. My goal is to eventually turn it into a shohin tree. The first two years I've mostly let it grow out in 3 gallon pot to put some girth on the trunk. I've done alright at that and the tree now has a 1" trunk which is respectable growth if not awe inspiring on its own. I'm now thinking about my plans for the spring and how I can keep making progress on the tree.

How it started:


How it's going:



It has some movement down low, I have some branches down low and I'm confident that I could develop new ones with the way that it shoots of new buds on the trunk.

What I'm worried about is the roots and the neberi which I really haven't done anything to help. My tentative plan is:

1. Spring 24 - Move into an Anderson flat. Start replacing the potting soil and lava mix with a more bonsai appropriate soil. Likely some "Classic Northwest Mix - Pumice, Lava, Bark 1/16” - 1/4” particle size" that I have currently on hand. It's relatively water retentive which is good for the water hungry redwood.
2. Spring 25 - Reduce the trunk to 4-5 inches above the soil? I could probably air layer and get myself two trees out of this, in the process.
3. Spring 26 - Start moving to smaller containers to eventually get it into a shohin container?

Maybe I'm trying to plan to far in advance but I like to understand what my general order of operations will be so I don't do to much to the tree at once.

Very nice thickness and plenty of ramification to choose from. Good luck!

Great growth very quickly! I'm looking to repot my Coast Redwoods this spring, and am deciding if i should go to a 10 gallon grow bag for trunk thickening, or an anderson flat for nebari flare/root control. I'm not going for shohin size though.
Mind me asking what the soil medium was for you to get to the 1" trunk thickness?

Its just in potting mix with some lava rock mixed in. It was not my most nuanced choice but seems to be mixed in. I can't even say I measured out the quantities.

Strong fertilization as well?

I hit it pretty good with biogild the year and I used liquid miracle grow last year.
