Sulphate of Iron contains ready-to-use granules ideal for acid-loving ericaceous plants. Sulphate of Iron makes soil more acidic, enabling these plants to take up the nutrients they need for healthy growth and development. For these special plants, if soils become too alkaline they suffer severe deficiencies when essential nutrients such as iron become unavailable. Sulphate of Iron enriches and unlocks these nutrients from the soil. It works best for rhododendrons, camellias, azaleas and hydrangeas.

Key features:

  • Richer, greener foliage
  • Strong Root Growth
  • Prevents leaf yellowing
  • Ready to use granules
  • Longer lasting flowers
