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.

    Lynne Calvert

    Would your inorganic bonsai soil mix combined with potting soil or peat moss be appropriate for Kokedama? Our garden club is planning a workshop. Thanks

      Hello Lynne,
      I am not qualified to answer that question. The best contact I know would be Martha Goff with Tropical Green Bonsai. She can be reached at this email [email protected] She can probably sell you pre-made soil as well.

    Plant Home Alone for Two Weeks: 6ft Ficus Lyrata Tree in Gritty Mix

    I am leaving my NYC apt for 2 weeks and trying to prepare my 6ft healthy Ficus Lyrata Tree in your 11011 Gritty Mix for “home alone” in best possible way.

    1) On Watering: With Gritty Mix, anything I could do to keep the water go longer without hurting the root?

    2) Some people seem to suggest to soak the tree(and let the planter sit in shallow water) and put it in a shade if one can’t water its tree for one week or two. But I am not sure this would work with fast-draining gritty mix and would two weeks with low to no light harm Ficus Lyrata less than water issue? Or shall I cut off most of the big leaves and don’t move the plant into a shade( Currently the tree is placed 5ft from the radiator and standing in front of a large south facing window)?

    Thank you so much!

      RE: Fiddle Fig. I would recommend re-potting after you return from the trip. The plants should be watched after re-potting until it recovers from the stress. I would also recommend adding some organic material to the soil mix as the Inorganic Bonsai Soil me be too dry for it. Pine bark or standard potting soil may help.

      You asked about automatic watering. Aqua Globes are great. The best solution is to pay someone to watch the plant. If you absolutely need to leave the plant you can partially submerge the pot in water to keep it moist. Try and keep it in the same light environment you have now. Leaving the plant unattended for two weeks may harm it. Many bonsai nurseries will offer boarding services. You can find a local nursery with our nursery locator here https://www.bonsaijack.com/nursery-locator/
      Have a great week
