Greensand 7.5 lb

Shipping Weight: 10 lbs
  Add to Cart:

Greensand, also known as Glauconite, is a mineral mined from natural deposits of glauconite located in the Southern part of New Jersey. These deposits are of marine origin and are composed primarily of iron-potassium silicate, which gives it its bluish green color.

Benefits of Greensand:

  • All natural source of potassium
    EspomaŽ Greensand
    contains 6% total potash, an essential nutrient required by plants that contributes to overall hardiness and good health. This potash solubilizes very slowly and therefore is available to plants at relatively small amounts at any one time.
  • Loosens clay soils
    The sand-like particle size and rounded shape of greensand helps prevent the interlocking of soil particles and thereby loosens the soil.


    Light Application 5 to 10 lbs. (or up to 1 cup for every 5 sq. ft.) per 100 square feet.
    Medium Application 15 to 30 lbs. (or up to 1 cup for every 2 sq. ft.) per 100 square feet.
    Heavy Application 40 to 80 lbs. (or up to 1 1/4 cups for every 1 sq. ft.) per 100 square feet.
    Per plant use 1/3 cup.

    Broadcast or spread Espoma Greensand evenly over the entire area. It is recommended that the greensand be incorporated into the soil before seeding or planting. For application during the growing season use the light rates shown above.
