When it comes to growing bonsai trees, choosing the right soil mix and substrate is crucial for the health and growth of your trees. Different species of bonsai trees require different soil compositions and substrates, so it's important to understand the specific needs of your tree and choose the right soil mix accordingly. Here are some tips for selecting the best soil for your bonsai trees:

Determine the specific needs of your bonsai tree
Before you choose a soil mix, it's important to understand the specific needs
of your tree. Some bonsai trees require well-draining soil, while others
prefer a slightly more moisture-retentive mix. Consider the species of your
tree, as well as its age and stage of growth, when choosing a soil mix.
Choose a soil mix with the right particle size
The particle size of your soil mix is important because it affects how well
the soil drains and how much air can reach the roots. Generally, a bonsai soil
mix should consist of particles of varying sizes, with the smallest particles
making up no more than 20% of the total mix. This allows for good drainage and
air circulation.
Consider using a substrate
In addition to a soil mix, many bonsai enthusiasts also use a substrate to
help improve drainage and provide additional nutrients for their trees.
Substrates can include materials like gravel, sand, or crushed lava rock, and
can be mixed in with your soil to create a more well-rounded growing
environment.
Avoid using regular garden soil
Regular garden soil is not recommended for bonsai trees because it doesn't
provide the necessary drainage and aeration that your tree needs to thrive.
Instead, choose a soil mix specifically formulated for bonsai trees, or create
your own mix using the right proportions of soil, sand, and other materials.
