This material is perfect formal upright material. One thing I notice right off is the crossing surface roots. That’s something you will want to correct for when repotting.

Maybe with a 'welcoming' branch that extend much longer than all the others... to differentiate from other JBP formal upright.

Agreed, though I do like the stereotypical “Christmas tree” formal upright JBP lol

And yes i was much more stressed than the tree. I hope that is one of the transgressions that might be overlooked for a new person to the forum

Well done solving the picture posting.
Tree looks fine and already has good spring growth. All that stress and anxiety for nothing but certainly par for the course with newer growers.
The roots look quite tight so I guess it has only had very minor repotting for some years. That can cause some issues with watering as it gets harder and harder for water to penetrate into root bound pots. Probably too late to do anything this season but you should be aware to monitor closely and make sure you water so that moisture penetrates right into the oldest parts of that root ball while not watering too often to cause waterlogging and root problems.

After you brought that up I was wondering If i could use kobob skewers To make some holes on the root ball until i can repot it properly. I have decided to let everything Grow unruly keep them alive till the late winter coming in 2023.

You should be fine to do a 1/2 HBR at this time of year in your zone. unless the candles have begun extending from the climate in California prior to shipping. that would depend on the location and elevation where the tree came from. If it were mine I would consider a 1/2 HBR now and if there is a strong recovery complete the second 1/2 HBR this fall to get the tree into free draining soil and well on the way for continued development.
The caveat would be how recently it was chopped and the current condition of the buds and or candles. From the picture it appears that those concerns would not be an issue.
I would suggest you discuss the possibility with the caretaker of the Bonsai at the Arboretum.

The picture shows that candles have not only extended, but are opening with the new needles. Apparently it was much warmer where it came from. Too late to repot now.

Is there a Wiki of terms, acronyms and abbreviations somewhere on this forum. I have been looking since last night for HBR to grasp what a 1/2 would be.

Half bare Root, a common method for repotting conifers and other species that require more care with repotting. There is a distinct difference between repotting deciduous generally compared to conifers.
With the half bare root process one combs out one side of the root ball replacing the compacted soil and dealing with removing badly tangled and some of the strong downward roots, but retaining the many smaller feeder roots as possible. The other 1/2 of the root ball is left for the next session.
it helps to get some assistance from an experienced person in order to determine the best portion to deal with the first time. Essentially it helps if you deal with the weakest side of the root structure the first time. This leaves the stronger side to fuel the recovery and then you have a strong recovered side to support the other side when it is completed. With a strong healthy tree this is often completed with 1/2 in the early spring and the other half in the early fall. Thus completing the repot and soil change out safely within one growing season. Other major work such as wiring, bending, styling is left until the process is completed and recovery has taken place.
My view of the picture shows newer growth with lighter color and older longer needles with duller blue green color. So that is why I suggested the OP consult with the local curator before deciding or proceeding. Pictures can be very misleading.
Young pines such as the one in the picture are very strong and can be worked within a very wide range of timing, not just the specific suggestions often repeated for guidelines.

Thank you for the explanation Of the term and what the process entails. There are alot of things i will not do without asking advise. This being right up at the top.

One perspective that I feel is important. The health of the tree is the first consideration but this should not prevent you from working the tree when it will benefit the tree. Leaving a healthy tree in poor conditions can only weaken the tree over time and create a larger problem. This is a prime example in my view. Steps can be taken that will improve the health and vigour for this tree. Simply by replacing the compacted field soil with proper free draining mix so essential for Pine health and future development. The tree is young enough, in good condition and the procedures are safe if properly carried out. If one is uncertain then smaller stages of work can be accomplished over a longer period of time. The bottom line is steps taken to improve the condition will pay off in the long run. Trees can be developed much faster if they are healthy and vigorous.Thank you for the explanation Of the term and what the process entails.

Proper root structure and health are the foundation for bonsai development and one of the most important topics to learn in the beginning. You are fortunate help is nearby in your location and wise to be seeking instruction and advise from the curator.

I was wondering and been looking around since last week. When you ask what style and said hint FU. Was FU meant to stand for fundamentals or a practice tree.

No, I meant formal upright as the trunk are straight and the branches are pretty evenly.
