My baby monstera deliciosa has been growing very rapidly lately and so I recently repotted it into a beautiful pot I bought while on a trip in Portland, OR. I think maybe there were some stowaway mushroom spores because now my soil has mushrooms growing in it that I just noticed when I rotated the pot for even sun exposure. What's the best way to remove them without inadvertently propagating them? Any other concerns I should be aware of? Thanks!

Yes, the potting mix you used likely was contaminated with mushroom spores. It is hard to know how extensive it is. But before you do anything radical, like changing the soil, there are a few things you can try.

First, gently scoop each mushroom out so you get the roots (called mycelium) as well as the mushroom itself. If you just pull it out, the fragile mycelium will remain.

Next, remove and discard any soil you added to the surface of the original rootball when you repotted.

Finally, allow the soil to dry as much as possible before you add any water. Mushrooms require constant dampness to survive. Warmth and sunlight will also deter them.

You may not want to use that potting mix again. Look carefully at the ingredient list on packaged potting mixes. It should list only peat moss, coir, perlite, and vermiculite. No compost, soil, bark or other ingredients that are not sterile and may harbor fungi and gnat larvae.

Thanks Will. I used the same potting mix I use for all of my houseplants and never had this problem before, which is why I thought maybe they came from the pot itself. I'm going to scoop them out this morning and report back.

@willC If I put the excess soil I'm pulling off of this plant in my compost outside, will it sprout mushrooms? I'm used to not wasting any plant matter, but I obviously don't want that happening.

Compost, bacteria, fungi (mushrooms), worms and other things we don't want indoors, are just fine outside.

These are in my mini garden and some other regular pots, and the fruiting only lasts for about 2 days. No action is needed unless the sight of them for such a short time really bothers you or, as the links mention, you have small children/pets who could reach them.
