Sticky Shiny Rose Leaves: Honeydew from Aphids or Whiteflies

A gardener noticed shiny substance on rose leaves. Jay identified it as honeydew—excrement from aphids or whiteflies after feeding.

Consequences

• Honeydew attracts sooty mold (black fungus) on leaves.
• Insects may already be gone—honeydew remains.

Simple Solution

1. Wash off with strong water spray from hose.
2. Check for live insects—if none, no insecticide needed.
3. Monitor for reinfestation.

Key insight: Visible honeydew doesn't mean current infestation. Washing is the first, best step.
