Bottlebrush bonsai

there are "official" names for different sizes of bonsai trees. Small, medium & Large is all you really need to know. The Japanese terms are mostly used when exhibiting bonsai. Different shows will have categories or classes for different size trees. This way the little tree in not competing directly against the huge monster. The most commonly used names are

mame bonsai = 4 inches and smaller in height or length from the rim of the pot.

shohin bonsai = 8 inches or less in height or length from the rim of the pot - note, the term shohin also includes all mame bonsai. Some will include trees to 10 inches, but it depends on your local show rules.

Kifu and Chuhin bonsai = medium size bonsai, I forget what the exact dimensions are, but Kifu is anything over 10 inches, and Chuhin starts a bit taller.

Dai and Omo and Imperial Bonsai - These are large, larger and largest. Dia is over 36 inches tall, Omo is usually classed as over 4 or 5 feet tall, and usually requires 2 or more people to move them. Imperial bonsai are so large and heavy that it takes 4 people to move a single tree around.

In North America, medium and shohin size bonsai are the most common. At shows the larger sizes often are the ones that win the awards. Big and Flashy often gets the judges attention.
 
Bottle brush do survive here in the winter. One year it actually snowed for a few days and a lot of bottle brush didn't make it. That's super rare, but I do plan on bringing it inside on nights that will dip below freezing. Again, pretty rare. As for the size it's actually about at what I'd like for this one. Next year after it recovers from the repotting I plan on cutting the thick branches back to the finer branches. When I dug down to find the nebari I was pleasantly surprised at how much flare there is. :) It's budding all over the place which is cool. I should have specified in my post that I'm just curious as to how I to encourage ramification in order to build secondary and tertiary branch scaffolding.

They respond well to any type of cuts, so the big cuts you plan on making should give you lots of new buds/growth to improve the structure and then after that I just dead head them after flowering. This stops them using energy to form seeds and they tend to bud out again shortly after giving new options. I also rub off any new buds I see that are in the wrong place and cut out any extra shoots that are not where I want them at the same time.Then leave them to grow until next flowering and repeat.
You probably could speed the process up by trimming more often but then you miss out on the flowers which frankly are worth the wait.

Thanks for the info. I'm pretty excited to see how this one goes. In other news; what the heck is going on in your avi????? 😆
 
I don't kill a lot of plants but I killed one of these. Bought in spring in a 3 gallon nursery pot. Pruned it hard and it went into a steady decline. Now all I have of it is about a 2 - 3 inch rooted cutting.

Okay, so take it slowly I guess. :/
 
Wired the structure on the bottle brush. This is my first go with rebar, so that was pretty fun. The larger branches will be cut off some time next year after it recovers from the repotting. Here's some before and after pics.
