I have this white powder on the soil of my polka dot Begonia. Is this beneficial or bad?

Looks like mold to me. I would scrape off the surface and try using a spray like neem oil or mix 1 part hydrogen peroxide to 2 parts water. I prefer Captain Jack’s neem oil spray because it prevents both pests and mold for me!

also to prevent this from happening, make sure your soil has some good aeration. Squeeze your pot (if plastic) to break up compacted soil or use a chopstick to poke down holes in the soil

Thank you. I’ll try this
