• Vegetable Gardens & Flower Beds: To prepare new gardens, apply 1-2 lbs per 100 square feet and thoroughly mix into the top 3″ of soil. To feed established plants, side dress 1-2 tablespoons per plant, depending on size of plant, once each month during the growing season.
• Containers: For new plantings, mix 1 tablespoon per gallon of soil and mix thoroughly OR add 1-2 lbs per cubic yard. For established plants, lightly mix 1-2 teaspoons per gallon into the soil surface once each month during the growing season.
• Trees & Shrubs: Spread ½ -1 lb per 1″ of trunk diameter around the base outwards to the drip line, mix into soil surface and water well. For new trees, prepare a transplant hole and mix ¼ – ½ cup with the backfill soil. Use amended soil to fill in around the new tree and water well.
• Row Crops/Acreage: Apply 200-500 lbs per acre depending on soil analysis, research data or specific crop needs.

• Improves Disease Resistance: Strengthens plant cell walls, enhancing resilience against diseases and pests. 
• Increase Crop Quality and Yield: Known to enhance fruit size, color, and taste, improving overall crop quality.
• pH Neutral: This naturally-occurring mineral does not alter soil pH to make it more alkaline or acidic.
