How To Identify Slime Mold

Slime molds are harmless fungi that feed on decaying organic matter. They live on the soil, thatch, or surfaces of grass foliage. During warm weather white, grey, or blacked masses grow over grass blades after a heavy rain or watering. Slime molds develop in streaks or small patches that smother, rather than consume, otherwise healthy turf. The masses then dry and form unsightly gray crusty mats.

 How to get rid of Slime Mold

Slime mold disappears fast and usually doesn’t occur more than once per season. We recommend either leaving it be, or raking, brushing, or spraying the grass blades to remove the mold. We do not recommend using any fungicide on slime mold as it is not necesssary.
