Feed Your Lawn Iron This September to Keep Moss Away

As the weather turns cooler in September, homeowners are advised to take action to maintain their lawns and prevent moss growth. Moss thrives in damp conditions, particularly when temperatures drop and rainfall increases, turning it into a potential problem for gardens. According to expert Kate Treen from Agrigem, a simple remedy exists for keeping lawns healthy and moss-free: feeding grass with iron.

Moss can create a spongy layer that not only poses a slipping hazard but also competes with grass for essential nutrients. This can lead to thinning lawns that struggle to survive the winter months. Treen emphasizes the benefits of using iron, stating that it lowers the soil’s pH to levels unsuitable for moss growth. She explains, “Iron is a great moss killer for lawns because it lowers the pH of soil to the point where moss is unable to grow and draws out moisture so mosses dry, turn black, and die. It also feeds the grass to encourage healthy green growth.”

Iron sulphate specifically is recommended as a highly effective solution for killing moss. It acts as a micronutrient that can burn moss spores while dehydrating them, leading to quick demise with minimal effort. Notably, while iron is detrimental to moss, it is safe for grass and can serve as a mild fertilizer. Iron plays a vital role in the production of chlorophyll, which is essential for grass to generate energy.

Implementing iron treatment not only strengthens grass blades and roots, making them more resilient against cold weather and fungal diseases, but it also enhances the lawn’s visual appeal. Increased chlorophyll production results in a deeper, richer green color, ensuring that lawns look vibrant throughout autumn.

To start, homeowners should select an appropriate moss treatment product. Treen highly recommends options like MossTop, Ferro-Gem Liquid Iron, High-Fe, or Feed, Weed and Moss Killer. It is crucial to apply the treatment on a dry day, as rain can wash away the product before it has a chance to work effectively. Following the instructions on the chosen product, moss should begin to die within a few hours, after which homeowners can rake away the dead foliage.

Caution is advised during this raking process, as damaging the grass can leave bare patches that may become susceptible to weeds later in the season. With proper application, lawns should appear greener and free of moss within just one day.

It is essential to understand that moss thrives in overly moist environments, indicating potential drainage issues within the lawn. To prevent future moss growth, aerating and scarifying the grass may be necessary, especially as soil tends to compact after summer.

By taking these simple steps this September, homeowners can ensure their lawns remain healthy, vibrant, and free from moss, paving the way for a stunning outdoor space through the autumn months.
