What's causing mold on my pothos and monstera?

All of my plants in soil have mold! At first, I thought it was due to me changing the soil and doing something wrong but even plants that I haven't changed the soil are growing mold as well. Idk what to do. I already changed the soil on a couple of them only for mold to grow again. I'm slowly converting to leca but some of these are big ones and I don't want to risk them dying. What can I do? What's the cause? #plants #mold #pothos #monstera #leca soil">#soil #sad #help
Usually that means the soil is too wet and/or lacking airflow. Most of the mold on the top of soil are harmless to the plant, but you do want to watch the plants staying overly moist.

Some people use hydrogen peroxide drench to kill mold or bacteria in the soil. If you have hydroguard for your leca setup, you could alternatively use that to help keeps your roots healthy in the moist environment from other bacteria.
Mold replicates by spores. They are microscopic and travel without notice. I'd venture to guess that your house has it recirculating through the ventilation even. There is mold all around us, all the time. But, I believe that if the soil you are using is staying moist for too long, that could be the reason the mold is taking up residence. It's okay....you can treat it instead of repotting everything.

Use a natural anti-fungal in the soil of your houseplants –

Cinnamon, apple cider vinegar, and baking soda are all excellent natural antifungal choices. Your houseplant will not be harmed by any of these products. They also sell products like leaf protectant, commercial anti fungal sprays, or you can make up your own. I made one up recently with white vinegar, water, and geranium, purification, and rosemary essential oils. Homemade leaf shine/protectant. 😁

Then, as time permits, you can start to repot your plants IF you want using fresh new succulent soil that has additional amendments like perlite, Leca, pumice, rice hulls, sand, etc. And add some cinnamon to the new soil as a preventative. I would keep newly repotted ones in a different room maybe, until you think the issue is controlled. Probably not necessary, but that would be me....obsessing.

I've never dealt with this issue, so this is not me speaking from experience...just what I've read/learned. Some other folks may have additional input. But if it's helpful information, I would appreciate you marking my response as "best answer" in the app. 😊
a few of mine do too. top soil mold is no big deal, you can sprinkle some cinnamon on it to protect your #plantbabies. the mold on mine is only on the plants with dense soil. make sure they’re not retaining too much water & if they are, repot with an airy soil, sprinkling cinnamon on your roots.

could you be overwatering?

I would try more ventilation with drainage
If the soil is too wet should I be adding more perlite then?
I had humidifiers going cause it says humidity is good. I also have a thermostat and I noticed it was saying that it was 'okay' in the living room withOUT the humidifier on. So I'm assuming it was okay without it being on, than more than likely, when they were on, it was causing it to be too wet in the house thus the mold?... I haven't had them in a week or so. I've put cinnamon on all the plants and I was already adding cinnamon to the soil beforehand. I guess not enough?

These plants are becoming harder to care for than kids.
