Indoor Mini Orange Tree: Sooty Mold and Neem Oil Fix

Indoor citrus (5 ft, 1-inch oranges) in warm, sunny office has black powder on leaves—sooty mold from insect honeydew. Wash off with soap and water, or use 100% pure neem oil which doesn’t wash off and protects from future insects.

Quick Fix

Wipe leaves with soapy water to remove mold.
Spray neem oil thoroughly, including undersides.
Repeat in 7–10 days if needed.
Monitor for aphids, scale, whiteflies—the real culprits.

Neem oil prevents recurrence.
