• As a 100% natural bone meal, the nutrients are released slowly into the soil as microorganisms break them down. This gradual release mechanism prevents nutrient burn and provides a consistent supply of food to plants over time.
• The added calcium contributes to stronger cell walls in plants, which can lead to improved disease resistance and better overall plant health.
• The ease of use, whether incorporated into the soil at planting or worked into the topsoil of established plants, makes it a practical choice for gardeners of all experience levels.
