Bacterial Leaf Spot on pink princess
What's Happening
Bacterial infection (often Pseudomonas or Erwinia species), typically spread by water splashing on the foliage or prolonged leaf wetness in humid environments with poor airflow.
How to Fix It
- 1
Isolate the plant: Stop the spread to other high-value aroids immediately.
- 2
Apply copper fungicide: Use a copper-based spray to halt the bacterial progression; follow label instructions strictly.
- 3
Prune infected leaves: Use sterilized shears (wipe with alcohol between cuts) to remove severely spotted leaves.
- 4
Improve airflow: Add a fan to increase air circulation and reduce the time leaves remain wet.
How to Prevent It
Avoid overhead watering; use bottom-watering or a long-necked can to keep leaves dry. Maintain a moderate humidity (50-60%) with active air movement.
