Fungus and Mold problem
I have a big problem with fungus I think. All my plants get this white substance on the top of the soil. Some plants seems to have the same fluffy white thing in the roots. some of the fungus seem to be very fluffy like... I have no idea what all this is. Also one of my plant has yellow mushrooms growing so im gonna just throw all the plant away. But the other plants have a different soil and i dunno whats wrong with htem...
Two things some to mind. If the soil stays wet too long, you will see fungal growth. Fungus is part of soil microbiome and is in the soil naturally. If you are over-watering, it will grow quickly. Like mushrooms that pop up, fungus isn't dangerous and doesn't make the plant poisonous. Just don't eat it. White fluffy also describes two insect pests, mealybugs and some scale insects. https://www.gardeningknowhow.com/plant-problems/pests/insects/mealybugs-control.htm
