Redevelopment of a trident maple

4 years back I made a conscious decision to improve one of my favorite tridents. It was a nice bonsai already but I felt the pot it was in was too deep and was overpowering the trunk. To improve this I had to airlayer the tree off the old roots to create a new shallow root system. This would allow me to plant the tree into a much shallower pot. Below are the results.

The tree now in March 2020.

The tree before, the pot having to be deeper to accommodate a large root system.
