Who Should Use Down to Earth Bone Meal 3-15-0

Phosphorus, Calcium, and Bulb Planting

Bone meal provides phosphorus and calcium — two nutrients linked to root development, flowering, and early plant establishment. Apply bone meal when preparing planting holes for bulbs or transplanting flowering ornamentals, working it into the soil at the root zone. For established plants, apply around the drip line and incorporate shallowly. Phosphorus supports root growth and energy transfer within the plant, while calcium contributes to cell wall integrity and supports soil structure.
