This is typical of Cleros and it is one of the reasons why the species is such a good bonsai subject. An abundant capacity to shoot back on bare branches makes for easy bonsai development.
At separation it had a very good root supply and so in the last two weeks and has firmed up nicely in the pot. It's prime time to get on with the next stage of the rejuvenation work.
The branch structure is also pretty poor. Not nearly enough branches is the common failure of many bonsai. That trunk really deserves better and so I'm going to have to start again from scratch. When the tree was collected there were branches cut off leaving a number of flat faced scars and deadwood. The existing branches developed from the callus tissue that formed around these old cuts.
In repeating that process of branch renewal it is likely that new branches will again come from callus around new cuts and I may not get enough branches again. If that happens then I'll use grafting to get the right number and location of branches. I have lots of cuttings struck in small pots ready to go for just that purpose and over the next couple of weeks will get them ready for hairpin grafting.
