Can you tell me how to kill fungus in houseplant soil?


Answer by  Bugturk (97)

Houseplant soil holds water exceptionally well. Fungi need a moist environment. So, unless you're able to hold off on watering for a few weeks, you're stuck. There are mild fungicides you can purchase, but the best answer is to replace the soil. You could bake the old soil dry on a cookie sheet, but it's probably not worth the effort.

Usually if you have fungus on the soil of house plants it comes from a mix of something in the soil mixing with something in the air the other thing that can cause it is have to much moisture in the air it can be caused from using things such as a humidifier.

If it's warm spread soil out in a shallow container, cover it with clear plastic and set it in the sun for about three days. You can also bake soil in your oven. Use a thermometer to make sure the soil reaches a minimum temperature of 200F. This will STINK.

It sounds like the soil does not currently have houseplants in it, but you would like to sterilize it for future planting. If this is the case, put it the soil in the oven at 250 degrees Fahrenheit, for a half hour or so. It will cool free of fungus.
