Enhance soil fertility and promote strong root development with Calphos Soft Rock Phosphate (5 lb), a natural source of phosphorus and calcium. This slow-release mineral fertilizer provides essential nutrients that support plant growth, improve flowering, and encourage fruit and vegetable production. Ideal for organic gardening, it gradually breaks down in the soil, supplying a long-lasting source of phosphorus without the risk of leaching.
Phosphorus is a key nutrient for root establishment, energy transfer, and bloom development, making Calphos an excellent choice for root vegetables, fruiting plants, and flowering ornamentals. In addition to phosphorus, this soft rock phosphate contains calcium, which strengthens plant cell walls and contributes to overall plant resilience. Together, these nutrients support vigorous plant growth and improved yields.
Easy to apply, Calphos Soft Rock Phosphate can be mixed into the soil before planting or used as a top dressing to provide continuous nourishment throughout the growing season. It is suitable for vegetable gardens, orchards, flower beds, and general soil improvement. The finely ground powder ensures efficient nutrient absorption, helping plants thrive in a variety of growing conditions.
