How to Use Greensand in Your Organic Garden
The amount needed will depend on where and how you want to use it. Trees: Use 1-2 pounds of greensand per inch of trunk diameter. Spread evenly over root zone. Plants: Use 1-2 pounds per plant, depending on size. Mix into the top six inches of soil. Broadcast application: Use between 50 and 100 pounds for every 1,000 feet of soil treated.
How to Use Greensand in the Garden
Trees – Work 1-2 cups of greensand into the soil around the base of the tree. Lawns – Use a broadcast application of 10-20 pounds per 1,000 square feet. Flowers and Vegetables – Apply 25-30 pounds per 1,000 square feet. Container Plants – 2-3 tablespoons per gallon of high-quality potting soil.
