And what about soil pH and species. What about peat moss? Does
every
specie tolerate it?

Different plants _prefer_ different soil pH. Virtually ALL
plants will grow in soil that has a neutral pH. The major
exceptions in the bonsai world are the Rhododendron and
Vaccinium, both of which prefer quite acid soils (and would like
a little peat in their soil), and (most) juniper which will do
best with a slightly alkaline soil. (HOWEVER, both of these
Genera will do just about as well in a neutral pH soil.)

So, discussion of pH in bonsai pots is much ado about not much
and I would not lose ANY sleep worrying over it.
