Ming Aralia Brown Spots: Likely Cultural, Not Bacterial

Brown, blister‑like spots on ming aralia leaves with yellowing are rarely bacterial or fungal indoors. More often they stem from a single episode of over/underwatering or a temperature drop.

Diagnostic Steps

1. Check for scale (scrape off, honeydew present) – not described here.
2. Review recent care: cold draft? Soil kept slightly too damp for weeks?
3. Overwatering is the hardest to detect—no dramatic wilt, just slow root decline.

Action

• Adjust watering: let top half of soil dry before rewatering.
• Keep temperatures stable, above 65°F.
• Do not treat with fungicide unless a lab confirms pathogen.

New growth will be clean if the stressor is removed.
