Stromatolite Watering Stones

Stromatolites are fossilized deposits of cyanbacteria and are composed of mainly calcium carbonate. Calcium carbonate is used to help prevent various diseases, like mildew, black spot, and rot. Calcium also increases metabolic functions in plant cells, allowing a greater intake of other nutrients such as nitrogen and phosphorus. It will also raise pH in acidic soils.
