Bonsai Lava Rock


    Our Bonsai Lava Rock makes a stylish topping for your succulent arrangements and terrariums. This is the same lava rock or pumice that is often used for bonsai trees, due to its ability to increase air flow in the potting soil while holding tiny amounts of water. Our bonsai-quality lava rock is harder to find and goes through a higher level of quality control. That means the extra dust has been filtered out and the size and color of each rock is more consistent, measuring roughly 1/4 inch. The lava has also been thoroughly disinfected, so it’s safe for your terrarium project. Add a bag to your terrarium kit for a classic zen garden look.

    Each order comes with 2 cups of jet black lava rock, which is enough to top off 1-2 large terrariums.
