Red Lava Rock (9–15mm)
Drainage • Aeration • Microbial Habitat
Red Lava Rock is a naturally porous volcanic stone formed during eruptions and colored by the oxidation of iron-rich minerals. This lightweight, mineral-rich amendment improves aeration, drainage, and soil structure, while providing surface area for beneficial microbes to thrive.
Its coarse texture and fast-draining properties make it an ideal addition to custom mixes for drought-tolerant plants or as a decorative, functional mulch to reduce evaporation.
