- Useful Information
Sulphate of iron makes soil more acidic, enabling special acid-loving 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. Works best for rhododendrons, camellias, azaleas and hydrangeas.
What to Expect
Sulphate of Iron will create the right conditions for healthy plant growth, keeping leaves green and healthy and preventing leaf yellowing.
For best results: When planting out your trees and shrubs use a dedicated compost to give your plants the very best start.
