Zeolite - 1/8" by The Bonsai Supply - 24lb

Improve nutrient retention and support healthier root systems with Zeolite by The Bonsai Supply. Screened to a uniform 1/8" particle size, this premium mineral substrate is prized in bonsai cultivation for its unique ability to absorb, store, and gradually release water and nutrients back to the root zone.

Unlike many traditional soil components, zeolite acts as a natural nutrient reservoir, helping reduce fertilizer loss while improving nutrient availability between feedings. Its porous structure also contributes to excellent aeration and moisture management, making it an excellent addition to both conifer and deciduous soil blends.

The 1/8" size is particularly well suited for refined bonsai, smaller containers, and species that benefit from slightly increased moisture retention without sacrificing drainage.
