If you have noticed toadstools or mushroom growing in your indoor plants, don’t be alarmed as it’s the result of a humid, moist protected environment and not detrimental to plants in the short term. They are the fruiting body of the natural fungi occurring in the soil and an indicator the potting mix is too damp. Back off the watering immediately and only water when you stick your finger in the soil and it feels dry. Another indicator that soil is too wet is the presence of fungal gnats, a small flying insect that hangs around the base of plants. While the flying, Midge like insect is annoying, it’s the larvae that cause a problem feeding on plants roots. The best way to control them is to keep the soil on the dryer side, ensure there is good drainage and allow for air movement around the plants.
