This pinus mugo, which I styled last year - http://nikart-slo.blogspot.com/2010/09/jamadori-rusevje.html -got it's first bonsai pot today. Actually I wanted to wait with the repotting 'till next year, but the wooden box started to decay and fall apart. But I removed almost no roots and old mountain soul - that comes next year.
Also the pot isn't final yet. It's a bit too big and the shape still isn't right. But overall I'm happy with the progress the pine is making.
