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


    Hello, I am looking for soil so I can grow a Ficus benghalensis from a seed. Would this soil or inorganic shoshin soil be preferable for germinating and growing my tree for the first two years.

      Hello. Seeds should be germinated in a high quality potting soil. Save your money. Bonsai soil is expensive and should only be used for finished bonsai material. Here is why…

      Most seeds do not do well in bonsai soil. Bonsai soil and pots are the last step to creating bonsai. Pre-bonsai should be developed and fully styled before placing them in a bonsai container and soil. This is because bonsai soil and containers limit growth. What takes 1 year to develop in the ground can take 10 years in a bonsai pot.

      One exception would be plants that are susceptible to nematode infestations like the Brazilian Rain tree and Bougainvillea. We propagate these in sterile soil or mystery mix(rejected bonsai soil that has never touched the ground). This ensures the plant never comes in contact with a nematode. The worst thing for a tropical grower is to work on a tree for 6 years only to find it has been infested with nematodes. Regular potting soil contains any number of pathogens. We sterilize the soil and reintroduce good organisms using soil from an established plant that has been proven to be nematode free. This only needs to be done on a few types of plants.

      I hope this helps.

  2. Question

    Julia Christie-Robin

    Hello, I recently inherited a miserable euphorbia xylophylloides. It’s currently in Hoffman bonsai mix and while I don’t want to knock them, I suspect the pH may not be ideal for this species. It looks emaciated and drops leaves daily. What would you recommend for this?
