Molds for bonsai

Molds for bonsai:

The soil for bonsai is composed with some elements, mixed in a different way for each type of plant we want to cultivate. In general a finer gravel is used, which can be zeolite, lapillus, or pumice stone; and gravel with a coarser grain size. Most of the substratum is made up of akadama, a soil made up of clay and mixed and cooked nutrients, also of fine or coarser grain size. To these components is added peat and humus soil, which consists largely of sphagnum or leaf mold.
