It can be frustrating to find out that your lawn has been affected by mold. The fungus can appear as gray spots, orange-red powder, fibrous red threads and irregular brown spots. If you have mold in your lawn, it is best to take quick action to prevent it from spreading. When you have determined which fungal disease is involved, you can choose a treatment method. Also take steps to prevent mold in your lawn, because prevention is better than cure.

Method 1 of 3: Recognizing fungal diseases

1. Look for thin, irregular spots that are white, yellow, or brown in color. It may be irregularly shaped spots or rings. You can probably see the soil through the grass, and the grass looks frayed. The spots are likely to get bigger over time.
2. Look for gray, black, orange, red, or purple spots on blades of grass and stems. This could be a sign of leaf spot, a fungal infection that spreads down the blades of grass, causing the roots to rot. The grass will eventually die. The fungal infection will spread further across the lawn if you don't do anything about it.
3. Look for a gray, black, or pink powdery or threadlike coating on the grass. This can indicate red thread, the pink grass crust or powdery mildew. Red thread and the pink grass crust are common and spread easily. Powdery mildew can also spread over the grass, but is less likely to penetrate the soil.
4. Watch for grass that has become dark, wet, and slimy. This means that your grass has been affected by the pythium fungus, which usually occurs in humid environments. If your lawn has been affected by this fungus, you may also see white, cottony fungi growing around the slimy area.

Method 2 of 3: Treating fungus in a lawn

1. After aeration, apply an annual top layer on the lawn. That means applying a layer of rich, well-permeable material to improve the quality of the soil. You usually use materials such as sharp sand, loam, peat and compost. The coating can make your lawn healthier and allow it to pass through more water, so it doesn't get soaked. Spread the cover over the lawn and rake the material over the soil to apply an even layer.
   • Before applying a top coat, it is important to dethatch and aerate the lawn.

Tips

• Choose a type of grass that fits well with the Dutch climate and the soil in your garden. Native grasses are more resistant to native fungal spores. Many exotic grasses are poorly resistant to these spores.
• Brown spots in your lawn do not always indicate mold. They can have other causes, such as dry weather, nutrient-poor soil, an insect infestation or animal activity.

Warnings

• Handle the fungicides you use with care and use them according to the directions on the package.
• Keep people and pets away when using a fungicide. Make sure that no one comes near the treated area after the treatment.
• Use caution when using a chemical fungicide as it can be harmful. For the best results, remove the treated area for several days after the treatment.
