I really like first branch very low, specially in
Ficus.
Now I would like you to consider some basics about your tree (and bonsai in general):
A. Unless you are trying to have a father-son structure, or double trunk, avoid the tree to grow from the roots.
B. Branches never grown in a wheel radius shape. In every floor, one only branch predominates and kill the others. So, one branch per floor.
C. There are things in a tree that you could easily change (branches) and others with a lot difficulty to be modified (nebari). Work in roots is continued.
I understood you have not very much experience with trees, so I will suggest you a couple of things to do safely and will help you to improve your skills.. If it's not this way, I'd be sorry cause I misunderstood you because English is not my mothertongue language!
1) you need to cut the son that is growing from the roots, and a part of the first (ichi) and second (ni) branches as they are doubled..
2) low the first and second branches. The firsts branches of a tree are pretty heavy. You may use a 1.5 mm wire, it would be perfect with your tree. I attach a photo of my own fig tree for you to analyze how..
3) after that I would change the pot. A bit wider one, but not too much wider.
- If you want your bonsai growing really fast, use a plastic strainer or a basket for clothespins. This will give the roots extra air, avoid large roots spiraling in the substrate and multiplying capillaries.
- Fulfill half the pot of substrat, put in there some flat surface (size a bit smaller than the pot, as an old CD), cut the main central root of the tree an maintain lateral roots.
- put the tree with roots in star shape directly over the CD ( this will make roots growing horizontally) and cover with substrat.
- You must water once at day.
4) cut all structure over the second branch. Try to maintain at least 1 inch over the branch anyway. In short your tree will give you a lot of new branches you could easily work with, and redesign your tree.
