I know, I know, soil sifting and mixing is a winter task. But with moving into and renovating the studio, it just didn't happen this winter.
I remembered to snap a couple of pictures as I worked.
Sifted akadama on the left, pumice on the right. These are 2-3 mm sized particles used for our main soil on medium to large size bonsai.
Lava being sifted. This is the third and last piece of our soil recipe.
