What is the best soil to use when re-potting my Bonsai Tree?
I would recommend either Akadama or Moler Bonsai soil, as these are pretty much the best Bonsai soils available. In a lot of cases such as with Chinese Elm’s you can use either medium straight out of the bag without adding other ingredients, however species that like more moisture would benefit from adding some organic compost and or bark chips (bark chips for Bonsai soil) to make the soil more water retentive. Please refer to the Bonsai Care Guides to see what type of soil your particular Bonsai species would prefer.
