- Inspect the undersides of leaves for small bumps.
- Look for sticky residue on the stems.
- Check if the white spots rub off easily with your finger.
Likely causes
Scale insects
Most likelyHow to tell: You will see small, hard, brown bumps on the stems or leaf veins that look like tiny shields. They do not move and often leave a sticky residue behind.
What to do: Scrape the insects off gently with a soft toothbrush or cotton swab dipped in rubbing alcohol. Follow up by spraying the entire plant with neem oil once a week for 3 weeks.
Powdery mildew
PossibleHow to tell: This looks like a dusting of white flour on the surface of your leaves. It happens when there is poor air circulation or high humidity.
What to do: Wipe the leaves clean with a damp cloth to remove the spores. Increase airflow around the plant and avoid getting water on the leaves when you water the soil.
