Woke up to find this bright yellow, frothy patch on my mulch. It appeared overnight and looks like expanding foam. Any ideas?

Preventing future slime mold blooms involves managing the moisture levels and organic content in your garden. Ensure that your mulch is not too thick, as a thinner layer allows for better drying and air circulation. Regularly turning the mulch can also help by disrupting the mold’s growth.

Consider using mulch types that dry out more quickly after rain, such as straw or pine needles. Improving drainage around your garden beds and avoiding excessive watering will also create less hospitable conditions for slime mold.
