Naturally occurring in marine sedimentary deposits, Greensand is composed primarily of the blue-green siliceous mineral glauconite. Traditionally used to loosen heavy clay soil or to hold together loose sandy soils, Greensand is able to absorb up to one-third its weight in water to improve the moisture holding capacity of garden soils and potting mixes. Greensand is highly recommended for vegetables, fruits, herbs, lawns, ornamentals and all types of trees and shrubs.

  • Improves moisture holding capacity of garden soils and potting mixes.
  • Apply at 1-2 Tbs/plant pr per gallon of soil, 5-10 lb/100 sq ft, or 500-2000 lb/acre, depending on soil analysis.
  • Apply 1-2 lbs. per 1 inch of trunk diameter around the base outwards to the drip line
