I didn't reverse my opinion. A tree can be stressed even if it is healthy. There are bonsai artists who say that old, finished specimens can be kept without repotting 20-25 years. This way, the tree will grow much slower and it's shape would be easier to keep. This is what I meant by "stressed", it is healthy but slowed down. You could have figured that out if you read what I wrote without being so angry because some newbie criticised you. The rank and time spent on this forum don't matter, the ideas do. Or do you think that people who are not old characters here can have an opinion? I'm sure there are great bonsai artists who don't come on this forum
