Proprietary soil mix resulting from more than 100 lab tests. Bonsai Jack bonsai soil mixes are optimized for pH, water absorption, evaporation, bulk density and particle size.

The soil mixes absorb a good volume of water and release more than half it over 24 hours. More than 80 percent of the water is released over 48 hours. This helps prevent wet feet and optimizes the wet / dry root cycle.

We understand the importance of trusted and safe bonsai soil mixes for your prized bonsai. Our bonsai soil products are backed by real science. You will not find us making claims such as “pH neutral”. We do not use fuzzy math(measuring with cups, dry quarts or nursery pots) when measuring soil for packaging. Our soil mixes are not simply created by throwing infested soil ingredients into a bucket. We source and process bonsai soils with professional standards.

  1. Question

    Rena A

    I’ve been struggling with fungus gnats and even though I don’t water my plants (all are succulents) more than 1 x month, the fungus gnats are still there. I would like to re-pot my plants in a mix that does not have any organic matter that fungus gnats can feed off. Can this particular potting mix be used for succulents?

      Thanks for the message. I would start by addressing the gnat issue. Please visit your local Ace hardware and ask for a small bottle of bifenthrin. This is the main ingredient in most over the counter insecticides. A small amount will go a long way. We use a bifenthrin drench when needed. A new soil will not eliminate existing pests. Good watering habits, insecticide and good watering habits will.

      I hope this helps. Have a great week. Please call or email if you have questions or concerns.
