I know they’re too wet, I’m letting them dry but I’m in a financial bind currently, and I have a super tiny apartment with only 2 sunny windows and I have over 20 plants inside so I am in a rotation right now.
I can’t afford to go buy new dirt currently to repot so I will scrape the tops off
But does anyone have any hacks for household products I might already have here to treat?? I also have neem oil for my outside garden but haven’t used on inside. Any tricks are appreciated!

A mild peroxide spray will help
Watering less is cheap. Overwatering is the common cause for mold on soil.
Peroxide.
I would remove the soil from that pot and put it in a nursery pot. Even if it has a hole, they just arent optimal for anything but a cache pot. If its not using the water, dont water so deeply. Light does speed up the usage, so if the plant is not getting as much, usage slows down.
The soil mold won’t hurt your plants, so you can just leave that be if you want, it should go away for the most part if you fix your watering.
I’ve had some success with sprinkling cinnamon on top of the soil
Just mix peroxide and water.
You can either spray it on the surface, or if you’re lazy (like me) – just wait until your next watering day and use the mixture to water the plant (carefully avoiding the leaves).
You can use as little as 1:9 peroxide ratio or as high a 1:1, but never use more peroxide than water unless you have a serious root rot problem; it’s overkill for a mile mold issue like this.
That said, watering less will also help stop this from occuring and lower the risk that one day it *will* be root rot
diluted vinegar, but ya just water properly instead
Sprinkle cinnamon. Seriously.
Scrape the mold off top. Sprinkle soil with cinnamon and let soil dry out to about 1/2 before you water again. If you haven’t already, you may want to amend your soil with extra perlite and orchid bark for better aeration. Also, Sanseveria like many plants prefer a smaller pot and produce more growth when feeling snug in their pot. Hope this helped! 🙂
Peroxide spray. You can apply cinnamon to the soil too to keep it from coming back
If mold is growing in your potting mix, it might be due to the mix being damp too often
Spray with 3% hydrogen peroxide or 6% but don’t get it on your fingers
I just slightly dig it with a fork. Shuffle it around and its new again.
Leave it and water less
That kind of mold usually means you have good soil. I would wipe it off your plant tho… I personally haven’t had it spread onto the plant
Just mix it around with the top 1″ of soil with your hands and call it good. Plus aerating the soil a bit will help keep it from staying so wet
scrape mold off cinnamon. I also like to put a small amount of rocks/pebbles on top of my soil. Makes all my plants look nice. But you still need to pay attention to dryness.
