It produces the spores in a manner similar to the fungi. Slime molds do not feed on living plants. They only use them for support during reproduction. The only damage they do to grass and other plants is to shade them from sunlight, which is necessary for good plant growth. When the fungus-like growth is real heavy, the shade it produces may cause the leaf blades to turn yellow.
Slime molds occur during wet weather throughout the spring, summer, and fall.
They disappear rapidly as soon as it becomes dry. In most cases a control is not necessary. If the growth is objectionable, you can readily break up the masses by sweeping with a broom or by spraying with a strong stream of water. During prolonged damp weather, when slime molds can be especially annoying, it may be desirable to apply any good garden or turf fungicide to affected areas.
