Enhance your potting mixes with Soil.Ninja Coarse Pumice 2.5L, a lightweight, porous volcanic rock that delivers superior drainage and aeration for healthy root development. Its irregular, airy structure allows excess water to drain quickly while still retaining small amounts of moisture, ensuring roots get the oxygen they need without becoming waterlogged.

Perfect for succulents, cacti, bonsai, and aroids, coarse pumice also benefits any plant prone to root rot or in need of improved airflow in the soil. Naturally pH neutral and long-lasting, this mineral amendment won’t break down over time, helping you create a stable and well-balanced growing medium. It can be used as a standalone substrate for certain species or as part of a customised soil blend to suit your plants’ needs.
