Calphos Soft Rock Phosphate (5 lb bag)

Calphos Soft Rock Phosphate in a 5 lb bag is a convenient choice for raised beds, planting holes, and smaller garden projects where a soil test indicates a need for phosphorus and calcium. The finely ground mineral amendment releases nutrients gradually and can be incorporated before planting or blended into compost. Suitable for vegetable beds, flowers, bulbs, and perennial planting areas, it provides a smaller quantity for precise planning without storing a bulk bag.

• Approximately 20% P₂O₅, including 3% available phosphate
• Approximately 18% calcium
• Compact size for targeted applications
