Though unsightly, slime mold is not a real threat to your plants. It feeds on bacteria and fungi within the organic matter. On turfgrass slime mold can block the sunlight from the blades of grass inhibiting photosynthesis. Consequently, the leaf blades may turn yellowish in color. Chemical control is not recommended for eliminating slime mold but changing the environmental conditions can be effective. Since slime mold grows best in warm, wet conditions, allow the area to dry out, if possible, by reducing irrigation. Patches of slime mold can also be scooped off the host and discarded. Areas of lawn covered in slime mold can be mowed and the clippings bagged and disposed. (Cynthia Domenghini)
