Healthy leaf comparisonAllow for normal differences in cultivar, leaf age, and sunlight while checking for spreading or structural changes.
  • LocationCheck which plant part, age of growth, and exposed or protected side is affected.
  • TextureDecide whether the evidence is dry, powdery, sticky, raised, translucent, soft, or intact.
  • ProgressionPhotograph the same area so you can tell whether the pattern is stable, improving, or spreading.

Use more than one clue. Confirm the photo with recent conditions, roots, watering history, and the rest of the plant before acting.

Honeydew is sticky sugary waste produced by sap-sucking pests such as aphids, mealybugs, scale insects, and whiteflies. On plumeria, honeydew often attracts ants and can lead to black sooty mold on leaves or stems.
