Scale Infestation on Schefflera: Sticky Leaves and Yellowing

Confirming Scale Insects

The sticky residue (honeydew) on leaves and carpet, plus yellowing and leaf drop, strongly indicate scale. Look for immobile brown, yellow, or green bumps on leaf undersides.

Treatment Plan

1. Spray leaf undersides with rubbing alcohol (full strength or diluted 1:8 with water) twice a week for several weeks.
2. Move plants to a sunnier location—full sun outdoors if temperatures allow.
3. If root-bound, repot in spring into a pot 2 inches larger.

Considerations

Scale is persistent but manageable. If plants are sentimental, commit to the regimen. Otherwise, replacement may be simpler. For detailed repotting or defoliation advice, a phone consultation can help.
