How can I effectively remove yellow slime mold from my houseplant soil?

To effectively remove yellow slime mold from your houseplant soil, you can gently scrape off the mold from the surface of the soil using a spoon or fork. Ensure the plant is not overwatered and the soil is allowed to dry out between waterings to prevent mold growth. Consider repotting the plant in fresh, well-draining soil to prevent the mold from returning.
