Moss can quickly invade your lawn, spreading through spores in the air and taking root in damp, shady areas. If you’re battling a moss infestation, a gardening enthusiast on Facebook has shared a simple yet effective solution: iron sulphate.
This readily available product is a popular choice among gardeners for its ability to kill moss and promote healthier, greener grass. Many members of the Gardening Hints and Tips Facebook group recommend using iron sulphate to tackle moss.
Lasma Styles, a group member, wrote: “Iron sulphate is used to green and toughen up grass as well as to kill off moss. No need to bother with fancy moss killers, this works like magic. In two to three days the moss has died. Then you can scrape the blackened moss out and enjoy your green green grass. You just need to dilute the iron sulphate correctly and not overdo it – too much is no good.”
Stewart Clarke, another group member, added: “Sulphate of iron will kill it off overnight. Use a watering can to put it on the lawn. It will go brown but the moss can then be raked off the lawn. Sulphate of iron will also make the grass greener and thicker.”
Chris Ivey provided specific instructions: “Use two and a half tablespoons of sulphate of iron, dissolve in one litre of hot water then make up to two gallons with cold water. Using a watering can sprinkle over the mossy area. In two days the moss will die and turn black so you can rake it out. The sulphate of iron will actually feed the grass left leaving it greener for you.”
Iron sulphate is widely available at garden centers and online retailers. One popular choice is Pro-Kleen Iron Sulphate, which retails for £13.95 at B&Q and £15.95 on Amazon. Customers praise this product for its effectiveness in killing moss within minutes while leaving grass and flowers unharmed. They also appreciate its ease of use and clear instructions. The product’s value for money is also highlighted, with many noting that it turns moss black within 12 hours. While some customers reported that the tub was not full upon delivery despite being advertised as containing 2.5kg, overall, iron sulphate remains a popular and effective solution for tackling moss in lawns.
By following the recommended dilution instructions and applying iron sulphate carefully, you can achieve a beautiful, moss-free lawn with healthier, greener grass.
