I recently moved my plants indoors for the winter, and I'm noticing some mold starting to form on the surface of the soil of a few of them. I've always used well-draining soil and usually water them well after letting them dry out, so this is new for me—especially since I just moved to a new apartment. It seems that the plants in my bedroom, which get more airflow from a ceiling fan, aren't having this issue. Could this be an airflow problem? Should I water them less deeply and focus on making sure the root ball stays healthy?

When I get mold on my soil, I usually just take a fork and stir up the top layer. It seems to get rid of it. You might also want to consider watering less frequently or try bottom watering instead to keep the surface dry.
Do you have a photo? It could be mineral buildup, but if it's mold, just spraying a mixture of water and hydrogen peroxide (2 parts water to 1 part peroxide) on the affected area can eliminate the spores. Also, what's your soil mix like? Does it have a chunky texture?
I had the same issue in my dorm! The ceiling fan made a difference for me. You might want to get a small desk fan near your plants for better air circulation, especially if they're clustered together.
Yeah, I'm considering that. They’re all on a plant stand together, so I think a little clip-on fan would help.
