Can anyone help me identify the mold growing in two of my potted plants, and how to treat them?
I bought the plants and potted them two weeks ago. The flowering plant is in a pot with a drainage hole at the bottom, and the succulent is in a glass jar with no drainage. Neither has any substrate gravel in the bottom. We used a combination of the two potting materials pictured below - "Miraclegrow indoor potting mix" and "Ecoscraps fresh start plant food".However, we did not clear away majority of the original soil around the roots of plants when we bought them.
The flowering plant suggest watering twice a week.
They sit in a glassed-in vestibule that gets lots of sunlight during the day (windows on the east and south side, and a clear ceiling). I moved them outside yesterday when I noticed the mold.
UPDATE: After moving the plants outside, the mold receded! Thank you SE for the analysis and help.
