Mold in indoor potting soil???

I have a houseplant question. Anyone have trouble with fungus/mold growing in the soil? I have never had this problem. I use to have all sorts of houseplants.. I am trying again, I hv switched pots, potting soil and tried adding a bit of hydrogen peroxide to my water.. of course, i cleaned pots real well when changing potting soil. My house doesn't get much sun. Is that it??

Usually it's a combination of too mucn water and not enough light.Using a little perlite in your potting soil can help the plants dry out a little faster.In Florida light really shoudn't be that big of an issue.Is your house actually dark or very bright,just no direct sun ?

As was said above its normally due to too much watering, although I've had the same problem this year and I think its the soil, because its only on the two plants which I potted in the new soil. Just make sure your plants are dry before watering - I waited until my two in question were almost dry and just scraped the top layer of the mouldy soil away - I only did this last week so its too early to say if its worked yet.

I have also had this happen with miracle grows cacti soil. All the time.

I store my Miracle Grow potting soil in a large plastic container with a lid in a dry place. Last month for the first time, I had half a box of it grow nasty green mold that was in the potting soil and had also gotten all over the inside of the storage box (which, btw, I clean each time before adding a new bag of potting soil). Wonder if there's a problem with Miracle Grow before we even buy it?

The bags of potting mix that you buy aren't sterilized, and even if you're keeping the container in a dry place there's usually some moisture in the mix when you buy it, so things like that can happen from time to time. It doesn't necessarily mean there was anything wrong with the potting mix--mold spores are everywhere and very hard to avoid, and if you have an environment where there's some moisture and the temperature is right then they can grow. If you want to avoid problems like that, then you can sterilize the potting mix before you put it in the container. Or else if the box could be vented a little bit that might let some of the moisture out and reduce the chances of stuff growing.

I buy the biggest bag of potting soil I can get so sterilizing would be quite an undertaking. But you likely hit on my problem ecrane. Hubby recently cleaned the room where I keep my box of potting soil and he snapped the lid down tight on it. I always just rest it on the box so it is ventilated. I will have to tell him not to shut it tight from now on (his intentions were good though). Thanks for the info.
