Pumice is an excellent soil conditioner, as it is highly porous volcanic rock, giving it excellent water and air holding properties. Advantages of using pumice in potting media and garden soils include:

—the porous nature of pumice allows it to hold vital nutrients in the microscopic surface pores, which helps regulate fertilizer feedings. It can even be supercharged with nutrients before it is added to the growing medium.

—excellent conditioner for soils that need increased aeration and drainage, as when growing cacti, bromeliads, succulents, or when rooting cuttings.

—loosens the density of heavy clay garden soils, letting in the air and water plants need.

—increases water retention in light and sandy soils.

—makes tillage easier.

—reduces crusting, cracking, flooding and shrink-swelling.

—holds moisture in the soil, reducing watering requirements, yet pumice will not compact or become soggy.

—pumice is inorganic, so it will not decompose or compact over time, meaning it functions continuously and can be recycled and reused.

—pumice is pH neutral.

—pumice does not attract or host fungi, nematodes, or insects.

—pumice makes an excellent component to composts, mitigating volatilization during composting and then contributing in-soil.
