Naturally occurring in marine sedimentary deposits, Down To Earth™ 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, DTE™ 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. DTE™ Greensand is highly recommended for vegetables, fruits, herbs, lawns, ornamentals and all types of trees and shrubs.
Vegetable Gardens & Flower Beds: Apply 5-10 lbs per 100 square feet and thoroughly mix into the top 3″ of garden soil.
Containers & Houseplants: For new plantings, add 1-2 tbsp. per gallon of soil and mix thoroughly or add 2.5-5 lbs per cubic yard. For established plants, lightly mix 1-2 tbsp. per gallon into the soil surface every other month during the growing season.
Trees & Shrubs: Spread 1-2 lbs per 1″ of trunk diameter around the base outwards to the drip line, mix into soil surface and water in well. For grapes, apply ½-1 lb to the soil around each plant and thoroughly mix into soil. For new trees, prepare transplant hole and mix 1-2 lbs with the backfill soil. Use the amended soil to fill in around the new tree and water in.
