Boost Your Garden's Growth with Soft Rock Phosphate 1kg

Soft Rock Phosphate (SRP) is a natural mineral powder that provides essential nutrients to your plants and improves the overall quality of your soil. This slow-release phosphate source works wonders for both outdoor and indoor gardening, resulting in healthier plants and increased yields.

Features and Benefits

  • Slow release: SRP delivers continuous nutrition to your plants, ensuring that they receive the optimum amount of essential nutrients throughout their growth cycle.
  • Long-lasting: Its non-leaching properties mean that SRP stays within the soil, providing lasting benefits for your plants and the soil health.
  • Soil improvement: The addition of SRP to your soil strengthens its structure and improves its tilth, leading to a more fertile and well-aerated growing medium.
  • Rich in essential nutrients: With 9% Phosphorus, 25% Silica, and 19% Calcium, SRP delivers the critical elements needed for a productive flowering and fruiting period.
  • Enhanced trace elements: SRP's abundant supply of trace elements supports healthy plant growth and enables them to reach their full potential.

How to Use

  1. Measure the appropriate amount of Soft Rock Phosphate based on your growing medium size – 1.5 cups per 75L for the first application with a subsequent 1/4 cup for each cycle, adjusting according to the nutrient demands of your plants.
  2. Choose your application method: top-dressing, mixing into the soil, or using it as a 'spike'.
  3. If top-dressing, simply scatter the SRP over the surface of your soil and water thoroughly.
  4. If mixing into the soil, evenly distribute the SRP throughout the soil and water thoroughly.
  5. If using as a 'spike', incorporate the SRP at regular intervals within your garden bed, penetrating the soil for deeper nutrient penetration, and water thoroughly.
