Further tips for the right formula for the soil:

• drainage must vary from species to species; it is therefore important to also take into account the environmental situation in which our bonsai lives;

• plants live in symbiosis with mycorrhizae. It is therefore useful to spread a layer of original soil in direct contact with the lower part of the roots;
