Saving Your Umbrella Plant (Schefflera) from Scale and Honeydew

Sticky leaves and small, barnacle-like bumps signal scale insects. They suck sap and excrete honeydew, weakening the plant and causing leaf drop.

Treatment Plan

1. Isolate the plant immediately.
2. Physical removal: Wipe scales off with cotton swabs dipped in 70% isopropyl alcohol.
3. Spray thoroughly: Mix 1 tsp mild liquid soap + 1 tsp rubbing alcohol per quart of water. Spray all surfaces—tops, undersides, stems—until dripping. Repeat in 7 days.
4. Systemic option: For heavy infestations, use a systemic insecticide (imidacloprid) as a soil drench.

Prevention

• Inspect new plants for 2 weeks before introducing.
• Check undersides of leaves weekly.
• Maintain humidity; dry air encourages scale.

Scheffleras are prone to spider mites too—look for fine webbing. Treat similarly with soap/alcohol spray.
