Rock Dusts

We carry a variety of Gaia Green® rock dusts derived from natural sources. Rock dust aids biological function in the soil and overall plant health. These finely ground products contain ingredients such as humic acid, glacial, basalt, and volcanic rock dust. Rock dust can be broadcast (spread) and cultivated into your growing area, or you can pre-mix it into your soil before potting or transplanting projects.
