Fine Black Lava Rock 1/8"-3/16"

Black Lava Rock plays a vital role in any bonsai soil mix. Its porous structure promotes airflow, delivering essential oxygen to your tree’s roots, this is critical for maintaining a healthy root system. The same porosity aids in efficient drainage, helping to prevent root rot, especially during prolonged rainy periods. This is the same black lava rock we use for our Shohin Bonsai Soil and TropiPon Micro mix.
