How do slime molds develop?

Organic matter in the soil is usually decomposed by a network of fungi, so-called mycelia. When this fungal network appears on the surface, it takes the form of slime molds. These can develop all year round

In the picture you can see what slime molds looked like on our lawn. These can have very different colors, from yellow to orange to purple. The pustule-like fruiting bodies of the mushrooms settle on the blades of grass.

Generally, slime molds do not damage the lawn and disappear by themselves as soon as it gets drier again. Of course, they don't look nice. If you want to prevent them from appearing, you should keep the lawn as permeable to water and air as possible. You can do this by regularly aerating and scarifying, avoiding thatch and using Turbogreen lawn aerator and regular fertilizing.
