Hello all! I haven a predicament. I have several houseplants with that white mold/spore on the surface of the soil. I have, in several cases, removed all of the dirt from the roots and gently washed them and then repotted to cure. But I have one plant where the mold reappeared and several new plants with the white crust on the soil. How do I get rid of this?! Is it killing the plants, or is it just ugly? Please let me know if you need a photo to help id! thanks, Kristina
