Lava Rock is a lightweight, natural volcanic medium that is commonly used in gardening.
This material's porosity and rounded particle shape allow for optimal drainage, improves soil aeration, and vigorous root growth, making it perfect for use in pots and beds. This allows for frequent watering without diminishing the amount of oxygen available to the roots. In regions where the water is especially chemically rich, lava rock can also operate as a natural filter.
Lava Rock's absorbency allows it to retain moisture and nutrients. The progressive release allows for a significant reduction in irrigation time while also assisting with water conservation.
