Down to Earth Oyster Shell
Down To Earth Oyster Shell
Down to Earth’s Oyster Shell is an all-natural and high-quality source of the essential plant nutrient calcium. Ancient oyster shells are carefully harvested and then ground into small, medium and coarse particles. These irregular shapes provide a sustained release of this valuable nutrient. Calcium promotes strong root development, improves nutrient uptake and boosts plant immunity. Down to Earth Oyster Shell also aids in improving structure of soils and building optimum tilth.
Application Rates:2 cups ≈ 1 lb; 1/2 cup ≈ 4 oz; 1 tbsp ≈ 0.5 oz
Vegetable Gardens & Flower Beds:To prepare new gardens, apply 2.5-5 lbs per 100 square feet and thoroughly mix into the top 3 in of garden soil in spring or fall. For new transplants, add 1-2 tsp per hole, mix into soil and water in well.
