I have a cherry blossom tree potted and recently bought another plant that I set on top of the soil (when I water it, the water drains through to the cherry blossom tree) I tend to be a chronic waterer and haven't watered them in a few days, came in the room to check and water my plants and saw this around the soil. Is this fungus? Eggs? Any ideas? I recently purchased mosquito bites and mosquito dunks and applied it to all of my plants because of a gnat infestation, which for the most part is completely gone. Between applying all that and watering appropriately I didn't expect anything else to pop up. Just trying to figure out what this new issue is. Thank you!!
