how to prevent lawn fungus

If you're proud of your lawn and keen to keep it looking its best, you should take steps to prevent lawn fungus. While it's true that the occasional toadstool can indicate healthy soil that's rich with cultures, a widespread lawn fungus problem can be damaging and unsightly. Today we're going to show you a few things you can do to prevent lawn fungus in your garden.


Mow regularly but carefully

During the spring and summer months, you'll need to mow your lawn once or twice a month. Be aware that cutting the lawn too short can make it more susceptible to fungus and diseases. If you want to give your lawn the best chance of fighting off fungus during the autumn-winter months, we'd recommend cutting it regularly through spring/summer, but keeping the grass long enough that it has strength and resilience.

Regularly sweep up leaves and debris

Lawn fungus thrives in warm, dark, damp environments, so leaving huge piles of autumn leaves or other debris on your lawn will encourage the growth of lawn funguses. It's important you give your lawn plenty of sunlight and expose it to the fresh air as much as possible, this will help excess surface moisture evaporate and will make conditions less favourable for all species of lawn fungus. 

Of course, if you like to use fallen leaves to mulch your lawn and add nutrients back into the soil, then you'll need lawn fungus to break the leaves down. So, this really is a question of preference. If you want to avoid lawn fungus altogether, we wouldn't recommend mulching your lawn. However, if you're willing to use lawn fungus to your advantage then you can allow fallen leaves to decompose and give their nutrients back to the soil.

Check and change your soil

The conditions and pH of your soil can have a huge impact on the quantity and types of fungus in your lawn. Fungus thrives in soil that's slightly acidic (eg. soil with a pH of less than 7). One way to change the pH of your soil and prevent the growth of fungus is to add lime. No, we're not talking about the green citrus fruit that tastes great in mojitos, we're talking about agricultural limestone! Adding finely ground limestone to your soil will make it more alkaline and will stop lawn fungus in its tracks.
