Would repotting be an idea? Maybe place it in a larger pot to give a little room. I will proun the dead away and put in full sun and watch the watering.. thanks again. I will post results as we go through this.
Maybe a slip potting, as it is now spring, but...
Only after you are sure your tree is healthy.
Don't do anything besides cleaning it and watering correctly until you see vigorous growth.
As an example, this below in a Japanese Red Pine I am growing; I live in Brazil, so now is Autumn here. I let it grow the whole season to get stronger, with no wiring, pinching, pruning or decandling, so next season (September is Spring here) it will take some insult from me.
It takes time, but this is bonsai...
