Sticky Leaves and Brown Nodules on Jade Plant: Scale and Honeydew

Sticky leaves + 1–1.5 mm brown bumps that scrape off = scale insects. The stickiness is honeydew; black sooty mold may follow. The nearby cyclamen had the same issue—likely the same infestation source.

Treatment

• Scrape off visible scales.
• Spray thoroughly with insecticidal soap or neem oil weekly for 3–4 weeks.
• Isolate from other plants.
• Wipe sooty mold off leaves with damp cloth.

Check all nearby plants; treat simultaneously.
