Green Fuzzy Mold on Umbrella Tree Soil: Algae or Mealybugs?

Green fluffy growth on pot edges is likely algae from moist soil surface, not mealybugs (white) or mold (usually gray/black). Your care sounds correct—bright light, proper drying, monthly rotation.

Email a clear photo to wcreed@HorticulturalHelp.com for confirmation. If it’s algae, simply scrape it off and let the surface dry more between waterings.
