Black dust on upper leaves (sooty mold) and bluish-white specs on undersides (scale insects) on a 6-ft potted Meyer lemon. Yellowing lower leaves indicate stress. Sooty mold grows on scale honeydew; it's harmless once scale is controlled.
Horticultural Oil: Spray thoroughly per label—causes burn if misapplied.
Manual Removal: Scrub scales with toothbrush and soapy water (tedious but effective).
Alcohol: Dab crawlers (white fluffy stage) with rubbing alcohol.
Move outdoors in summer; natural predators keep scale in check. Monitor regularly.
