Remove moss from lawns so that it's 'impossible for it to grow back' with 1 vital item

September is actually a great time for you to continue to enjoy your garden, and to roll up your sleeves and prepare your lawn for next year before the winter months set in. One thing that makes lawns problematic at this time is moss. In addition to causing visual issues, moss poses a risk to the health of your grass by occupying valuable growing space.

As it spreads, moss blocks vital water and nutrients from reaching your grass through lawn fertilisation. This leads to suffocation of your lawn and impairs its ability to thrive and remain healthy. Gardening guru Nick from Lawn and Weed Expert claims that the trick to restoring a lush and vibrant lawn is to use iron sulphate to combat the invasive moss. He explained: "When applied correctly, iron sulphate moss treatment should eliminate the moss while leaving the grass unharmed. It can also aid in fertilising your lawn: iron is a crucial nutrient for grass, just as it is for humans."

Iron sulphate serves as an environmentally friendly solution in turf management for eliminating moss and is essential for significantly enhancing grass health, allowing it to grow "thicker, fuller, and greener".

When applied, iron sulphate quickly goes to work by drying out the moss, leading to its death, while also adjusting the lawn's pH levels to create conditions that hinder moss from regrowing.

Nick noted: "Iron sulphate is the result of combining sulphuric acid (a strong acid) and ferrous hydroxide. Applying it to your lawn will lower the pH of the soil, past the point at which it's made impossible to grow back.

"Simply mix iron sulphate with water and spray on affected areas, then sit back and watch the moss blacken and die off."

The ideal moment to spread iron sulphate on your lawn is the day following rainfall, as the moisture in the soil enhances absorption for both moss and grass, making it more effective.

Using iron sulphate on a hot and dry day may lead to it resting on the grass surface instead of penetrating the soil, which could potentially scorch the grass.

Although iron sulphate is composed of natural ingredients, it's important to adhere to the guidelines closely during application and to refrain from overdoing it, as this could harm the grass.

Nick said: "Iron sulphate kills moss, but too much of the pure product can also harm your grass! Lime (the mineral, not the edible kind), bicarbonates, and zinc can all help combat iron toxicity."

After the moss has died, take a rake to collect any dead leaves and dispose of them correctly to avoid a moss infestation from coming back.

Nick added, "After a course of iron sulphate moss treatment, the grass will need to be scarified to ensure the dead moss doesn't linger. Your lawn may need to be given a booster of sorts. Lawn fertiliser will help here. You could also overseed your grass after using iron sulphate."
