Give plant roots the minerals they crave via glacial rock dust gardening. A byproduct of natural glacial action, this silt-like material is laden with the nutrients your garden needs. Add to compost, potting mixes or as a top dressing for plant containers and watch flowers, greens and edibles thrive.
Each 25-pound bag of rock dust minerals is intended for use as an organic soil amendment. The action of these nutrients is slow-release so that benefits last throughout the season. Use to nurture tree roots, rose and vegetable gardens, window box arrangements, patio planters, and more. See Additional Information below for the recommended amount of garden mineral dust per application.
