Answered
I need help, my house plants have mold on the top layer of dirt. I only water my plants once a week and only enough to dampen the water. I have 9 different kids of house plants. Does anyone have any ideas why I have mold on my dirt, or do you have any solutions to get rid of it? Below is one of my plants.

    My plants recently have done the same, so I was interested too to see what was going on. I think this gives us the answer, and you will see there are other videos on the subject.

    Different plants have different watering requirements based on size of plant compactness of the roots and the plant itself, For most plants you should water them really well- like until water runs out the bottom and then don't water again until the top 1/2 inch of soil is dry on top. Don't, however leave water in the bottom saucer--most plants don't like their "feet" constantly This means your once a week watering schedule becomes a once/wk checkup schedule. Keeping the the top only just damp might cause mold, Anyway scrape off the top inch of soil and replace with new potting soil and water well.

    I put cinnamon on my plants surface and it's all gone. Don't water so much and only water from the bottom. Set your timer for 30 min. Drain any left over.

    Mold will grow on almost any organic source, if the humidity is sufficiently high. Molds are generally created by filamentous fungi that are ever present in our environment. Each species can have different preferences for certain types of organic food sources, ranging from wood to plant debris.
    The molds which grow on peat moss and other growing media is saprophytic, meaning they feed on dead plant material and are not pathogenic or harmful to plants or people. The molds are found naturally in peat bogs at very low populations, but due to the acidic nature of a peat bog they do not flourish, which results in slow decomposition of peat moss. However, once harvested, and amended with Lime and nutrients this changes the chemistry.
    Generally reducing moisture, lowering the temperatures and improving drainage will help eliminate the mold.

    Just scrape it off and turn the remaining dirt over. Make sure the dirt dries completely before rewatering.

    Truthfully, the fungi or mold on the surface of my soil never harmed them at all
