I bought these mini roses a couple of months ago. I repotted them with indoor soil in a pot with one drainage hole, then transferred them to a smaller pot (second picture). I have them under a grow light, and I water them once a week. As the plant has gradually dried up, I pruned off all of the tried flowers and branches. A few days ago I noticed this white fuzzy mold on the soil. What should I do to revive this plant, get some growth and make the mold go away?
