Under certain conditions, larger accumulations of fungi can form in the lawn. However, even the owners of indoor plants are sometimes surprised by the fact that mushrooms suddenly grow out of the ground on the windowsill, seemingly overnight.

Fungal spores can be anywhere
If you want to grow mushrooms in the garden or in your own basement, you need mold spores for a soil or substrate inoculation from specialist shops. Conversely, fungal spores often get into some flower pots unwantedly with potting soil or through the air. Since many potting soils are enriched with wood or coconut fibers, they offer an ideal breeding ground for various types of fungi.
Symbiosis for the benefit of the potted plants
While many types of mushrooms that grow in pots are not human-edible species, they still serve a purpose. Valuable nutrients are created when the wood is broken down according to the symbiosis principle of the mycorrhiza fungi, which can promote the growth of flowers and other potted plants. Since there can sometimes be highly toxic yellow-leaved parachutists in plant substrates in addition to non-poisonous parachutists, these small mushrooms should be removed and composted if dogs or children are within reach of the pots.
Growing mushrooms in the pot
If cultivated mushrooms are to be grown in pots, a sterile substrate such as coffee grounds is required, on which edible mushrooms such as oyster mushrooms can also be grown in a pot with a bit of luck. However, boxes or bales of straw can also be used for growing mushrooms. The following things are usually required for growing edible mushrooms in the basement or in a dark shed:
- Straw bales, coconut fibers or other substrate
- a dark, moderately humid room
- Fungal spores for inoculating the substrate
tips and tricks
If fungi are a problem in the flower pot, they can sometimes be eliminated by replacing the potting soil. Due to the large spread of the mycelium, which is difficult to see, the entire soil in the pot must be replaced if possible.
