This plant was pretrained for its bonsai life but its center was still old potting soil. Last years watering was sometimes not as it could be. I went for a half bare root repot. Not totally confident it was the best choice. I had no time this year to do it under guidance so fingers crossed.

The remaining mix
After sifting to see how much was good particle size.

Bottom right: the size of the particles i used now. Last time we went a bit smaller to slow the tree down. Now i think it might be good to let it grow a bit more.
Top left, the finder but still ok mix.
bottom left, a little bit of akadama dust, but 90% is old potting mix from the center of the rootball. I'm happy it's out. Lets hope the tree is happy too.
