White powdery substance on SOIL in container garden.

Asked July 15, 2020, 12:14 PM EDT

I am seeing a “snow-like” substance on top of potting soul in a big flower pot where I planted coleus and impatience. The pot is in shade and watered frequently. I’m guessing it’s a mold of some sort. Can I treat the soil with something?
