I bought this Cedar from a garden centre many years ago as a very small shrub and had no success growing it as a bonsai although I did some initial branch placement. I gave up on it and put it into a large ornamental container with a view to growing it as a garden shrub. I had a look at it late last year and was really surprised at the way it had thickened up and matured. I thought that it might be worth taking it up again as a bonsai so I took it out of the container a few days ago and reduced the root-ball by about one third. I wanted to trim the tree foliage quite a bit so I did not disturb the roots very much. I also cleared the top soil to reveal the nebari and was very pleasantly surprised with what I found. The tree was put into a new plastic tub with a very free draining mix.
The tree has been trimmed but not wired in any way so as not to stress it too much at this time. I am quite pleased with the initial image which should improve greatly with time.
