      Hello. Thanks for the message. Gritty mix is probably not a good fit for your plant. I would recommend using a high-quality potting soil. The selection will vary by state. Gritty mix is very expensive to produce and should be saved for plants that require it such as succulents and bonsai.

      Have a great week. Please call or email if you have questions or concerns.

  2. Question

    Pamela Stegmaier

    Greetings,
    I like an inorganic soil mix, and grow Haworthias, as well as African caudiciform trees. I’ve used turface, pumice, scoria, and crushed granite in the past. Right now I’m stumped on the difference between Monto Clay & Bonsai Block(calcined clay). Could you tell me the difference between those two, and as compared to turface? I know the PH is different but they are both clay?? I just tried to make a custom mix with 40% Pumice, 15% Bonsai Block, 10% Charcoal, 10% Black lava, and 25% Monto Clay. What overall PH would this be?
    Thank you,
    Pamle

      Thanks for the message. Bonsai Block and Monto Clay are both clay products. Bonsai Block is a fired standard ball clay (often confused with shale) and similar to Akadama which is not fired. This is an alkaline ingredient. Monto Clay is fired montmorillonite clay with high CEC and acidic properties. I hope this helps.
