    Hi Joe –

    Rock dust improves soil vitality and plant health. It contains a broad range of trace minerals, many of which have been lost through the ages, by erosion, leaching and farming. We offer to types:

    Gaia Green Glacial Rock Dust which is derived from glacial moraines located in British Columbia, Canada.


    Azomite which is derived from a natural volcanic ash deposit mined in Utah.

    To apply spread 50-150 lbs per 1,000 square feet and work into the soil prior to planting. During the growing season, boost plant health by side-dressing in crop rows or around the drip line of trees and shrubs. It’s best to work side-dressings into the top 1-inch of the soil.

    Happy gardening!
