Hello all
Last year I sowed my first seeds, which where put in propagation soil, and later replanted to "young plant" soil.
So I was wondering when I should replant to a "real" bonsai soil mix (akadama, pumice etc.)? Is it now or should I wait another year or two?

Wait for the stem change color, to a mature brownish hue. It takes at least one year, but it depends on the species.

Okay, many thanks.
