From Cleenly, Iron Sulphate is a lawn feed designed to support stronger grass for longer, with a formula described as rich in iron. It can be applied dry or mixed with water, making it easy to fit into your usual lawn-care routine, whether you’re refreshing tired-looking grass or maintaining a greener finish.
For best results, apply just before rain is forecast to help water the granules down into the soil. When mixing, the guidance varies depending on your aim: for grass greening, use 1–2g per 1L of water; for turf hardening, use 2–3g per 1L of water. Apply 1L of solution per square metre of turf using a pump sprayer or watering can, then water down thoroughly with fresh water.
